Version numbering in deb inconsistent with our versioning scheme

I think according to our current versioning scheme we're working on version 0.1.0.

When installing the deb package, it prints:

Unpacking briar-desktop (0.0.1-1) over (0.0.1-1) ...
Setting up briar-desktop (0.0.1-1) ...

which looks like it has somehow a different version number set.
