Remove the watches a failed tree call had already added

A recursive watch that hit the watch limit or an unreadable directory threw after adding watches for part of the tree, which stayed in the instance and kept counting against the user's limit. The call now leaves the instance as it found it. The test needs a second instance for the check, because a repeated watch on the same instance only updates the existing one.

+The returned array contains one watch descriptor per directory. Subdirectories created **after** this call are not covered. When one of the directories cannot be watched, for instance because the user's watch limit is reached, the call throws and removes the watches it had added, so the instance is left as it was.
