mailinfo: stop using the_repository

Stop using `the_repository` in the "mailinfo" subsystem by passing in
a repository when setting up the mailinfo structure.

Adjust callers accordingly by using `the_repository`. While there may be
some callers that have a repository available in their context, this
trivial conversion allows for easier verification and bubbles up the use
of `the_repository` by one level.
