Fixes #816

Check the blog item in NavDrawer when opening a blog via notification

There are three scenarios where the selected item in the NavDrawer changes:
1. The user selects an item -> the item is checked automatically.
2. The user pressed back -> already handled in onBackPressed (needs to be extended with #606)
3. The user touched a notification -> handled by this commit.

Stop periodic list update only once

When testing the forum unread code, I noticed the recycler view is detaching twice. Once because the stop method is called and once because the view detaches from the window. Wouldn't it be safe to null the refresher when the updates are stopped?

Remove code for collapsing threads and for reply count

Besides removing lots of code, this MR also improves the encapsulation between adapter and view holders.

Threaded Unread Handling

![unread](/uploads/457c3bc36c897d683ff8161b4f3a344c/unread.mp4)

This leaves in the collapsing code for now and just hides the UI element for collapsing. The code can be removed in a second pass to simplify the adapter.

New Forum Sharing Client

This is very similar to how the private group invitations work and I am sure there's still some tiny bugs that I didn't catch.

All existing integration tests either pass or have been modified to pass.

Once this has been merged, the code should be usable for blog sharing as well.

Fix memory leaks caused by periodic view refreshing tasks

This branch implements @goapunk's suggested solution to #851. Credit goes to @ernir for finding the bug and the initial solution, and @goapunk for the improved solution - I just did a quick implementation so we can get this fixed as quickly as possible.

Merge branch '710-conversationactivity-uses-uninitialised-field-as-format-string-argument' into 'master'

Make sure contact name is initialized when needed

This uses a Listenable Future and unfortunately requires 4 basically identical methods to handle the incoming events. Any suggestions for improving that are welcome.

Unit tests for record readers

Add a handleDbException() method to BaseActivity

This adds a `handleDbException()` method to BaseActivity and a corresponding method for fragments that calls through to the activity.
For now, the method just finishes the activity
and NavDrawerActivity overrides it to do nothing,
and all the error places marked with TODO that finish the activity call the method instead.

That gives us zero functional improvement over the status quo,
but it allows us to change the default behaviour easily,
and then we can start thinking about which cases should have non-default behaviour.

Show open button in private conversation after accepting invitations

To keep the implementation simple, the Open button does appear where the Accept button had been previously.

In order to make the Open button functional, I had to make the `GroupId` of the invitation target available to the UI. Most code in this MR is due to that.
