Inotify is not updated when switching repo from bookmarks widget

[char101]

Hi,

As the title said.

I found that restarting inotify on cmds.OpenRepo do the tricks

class OpenRepo(Command):
    def __init__(self, repo_path):
        Command.__init__(self)
        self.repo_path = repo_path

    def do(self):
        git = self.model.git
        old_worktree = git.worktree()
        if not self.model.set_worktree(self.repo_path):
            self.model.set_worktree(old_worktree)
            return
        new_worktree = git.worktree()
        core.chdir(new_worktree)
        self.model.set_directory(self.repo_path)
        _config.reset()
        self.model.update_status()

        from cola import inotify
        inotify.stop()
        inotify.start()
