server-info: stop using the_repository

Stop using `the_repository` in the "server-info" subsystem by passing in
a repository when updating server info and storing the repository in the
`update_info_ctx` structure to make it accessible to other functions.

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.
