fix: deleted repositories linger until the cache expires

Deleting a repository left it on the list, and pulling to refresh did not shift
it. Two independent reasons, both cache-related.

deleteRepository never invalidated anything. Creation invalidates the
repositories and home prefixes; deletion was written without it, so the list and
Home kept serving a repository that no longer exists.

And forceRefresh only ever reached the build statuses — its own doc comment says
so — while the repository list itself was pinned to useCache: true. So a pull to
refresh re-served the same cache it already had. fetchPage already takes
useCache and falls through to an uncached fetch; it was simply never told.
