The PR should be fixing this uninstall/(re)install problem - it was added in #0330 so try #0329 and see if you can uninstall an add-on and then immediately reinstall the same add-on (or repository, but maybe repositories trip over a different code path which is why it remains broken for repositories?)

In #0329 it should be impossible to uninstall-then-reinstall an add-on, but should be working in #0330 (at least for add-ons installed from an online repository ie. official YouTube add-on).

I must admit I didn't try uninstalling/reinstalling an add-on from a zip, or uninstalling/reinstalling a repository from a zip - it's possible these scenarios remain broken (will test it myself later).
