1.0.2dev: only list languages for which there's a message catalog.

Previously we added to the list all the languages present in the
repository. But sometimes a catalog might not be compiled (e.g. if
marked as fuzzy), so better only propose a restricted choice
consisting only of the languages for which a `messages.mo` file can be
found.

Fixes #10855.
