Title: Return :warn instead of :fail on BundleCheck

When rebasing, returning `:fail` will abort rebase and the repository ends up with a detached HEAD. Rebase becomes impossible unless you install the needed gems first.

My solution for this is to return `:warn` since I think the bundle check status is a nice to know and shouldn't stop a rebase.
