branch: test for failures while renaming branches
When we introduced replace_each_worktree_head_symref() in 70999e9cec
(branch -m: update all per-worktree HEADs, 2016-03-27), we implemented a
best effort approach.
If we are asked to rename a branch that is simultaneously checked out in
multiple worktrees, we try to update all of those worktrees. If we fail
updating any of them, we die() as a signal that something has gone
wrong. However, at this point, the branch ref has already been renamed
and also updated the HEADs of the successfully updated worktrees.
Despite returning an error, we do not try to rollback those changes.
Let's add a test to notice if we change this behavior in the future.
In next commits we will change replace_each_worktree_head_symref() to
work more closely with its only caller, copy_or_rename_branch(). Let's
move the former closer to its caller, to facilitate those changes.
