bundlerepo: let bundle repo look in the _mancache
When looking up a base revision, we were ignoring the contents that were already
available in the manifest's _mancache. This patch allows us to use that data
instead of reading from the revlog.
This is useful in our pushrebase extension (which allows rebasing on the server
side during a push) because it allows us to prefetch the bundle base manifest
before aquiring the repo lock (1 second saving), which means doing less work inside the lock,
which means a 20% higher commit rate.
