Remove ShareWorktree message

Browse source 
Instead, create an empty worktree on guests when a worktree is first *registered*, then update it via an initial UpdateWorktree message.

This prevents the host from referencing a worktree in definition RPC responses that hasn't yet been observed by the guest. We could have waited until the entire worktree was shared, but this could take a long time, so instead we create an empty one on guests and proceed from there.

We still have randomized test failures as of this commit:
