Categories remain after disabling a repo.

• F-Droid version (in the About screen):

0.102

What did you do? (clear steps if possible)

• With the main F-Droid repository enabled, do a repository update.
• Note that there are appropriate categories, each with many apps inside them.
• Now disable the F-Droid repo and return to main screen.

What did you expect to see?

List of categories should only include:

• "What's New"
• "Recently Updated"
• "All"

What did you see instead?

All categories from the main F-Droid repo still remain.

This is because the decision to include a category in the list is based on the presence of an entry in the category-app-join table. If a category is joined to an app (e.g. if there is at least one app which is in that category) then it is a category worthy of showing. Otherwise, it should be ignored.

However, when the RepoProvider purges apps in response to disabling a repo, then it doesn't remove relevant entries from that join table.
