Prevent apt from being confused about mullvad-vpn package version

[MarkusPettersson98]

Sometimes, apt thinks that some installs are downgrades due to the dev version hash being lower than the baseline version hash. This PR makes the test framework add --allow-downgrades to apt when installing the app. To make sure that we are running the expected app version, a runtime check has been added to the test_upgrade_app test.

    // `apt` may sporadically consider installing a development build to be a downgrade from the baseline stable

We could be more specific about the bug behavior here just to document it somewhere, e.g. "apt may consider installing a development build to be a downgrade from the baseline stable if the major version is identical, in which case the ordering is incorrectly based on the git hash suffix"

That's a good idea. Updated the comment, please let me know what you think 😊

The Error::DaemonVersion variant is probably not needed, you could replace it with just a formatted error message.
