Subject: [PATCH 1/2] Fix crash on startup

This commit fixes the program crashing because of an uncaught exception.
The bug was triggered by app_settings.last_launched_version being
unset - which would always be the case when launching the program for
the first time!

The bug could also be triggered by manually changing the setting
to an invalid value - e.g. by running:
$ gsettings set com.github.geigi.cozy last-launched-version 'ayy lmao'

Subject: [PATCH 2/2] Remove usage of version.LegacyVersion

The "packaging" module has deprecated its LegacyVersion identifier back
in 2020, finally removing it in 2021. This causes cozy to crash when
running against new version of said module, with the following error:
> AttributeError: module 'packaging.version'
>                 has no attribute 'LegacyVersion'
