Prevent a crash caused by empty emoji

Closes #1015

See merge request !571

The crash happens because the serialization of recently used emoji uses
';' to separate the emojis.
One of the ASCII emojis however has a ';' in the beginning.
When this one is used by the user,
it causes an empty string to be returned when deserializing.

This commit prevents the crash by changing the separator to a tab.
It uses a different settings string to store the emoji,
so users will lose the list of recently used emoji when they update to
this version.

PS. That wasn't my idea ;)

Fix Blog Sharing Sessions

Closes #979

See merge request !566

to have all the code related to that in one place,
so it is easier to maintain and to spot bugs.

This also checks that only blogs without an existing sharing session
are shared and initialized again.
It extends an existing test to catch the missing check.

This removes some debugging information from the previous commit
to not leak private information via the sharing sessions.

Fixes #979
