  Make the adhoc add-on download check more detailed.

Originally this simply checked for whether the add-on's directory existed to avoid downloading the same add-on multiple times when migrating from one major release to another. However this then causes add-ons to not get updated when joining a multiplayer game where to person joining has the add-on (so the directory exists) but needs an updated version of it.

Fixes #6383
