maildir: fix handling of FSEvents

Maildir uses a filesystem watcher to watch the currently selected
directory for changes, updating the UI as necessary. Not all changes get
updated based on the current logic. Send a MessageInfo if the event was
a Rename. Send a MessagesDeleted if the event was a Remove. Tell the UI
to refetch the list if the event was a Create.

Note: This leads to some unnecessary fetching in the UI, as renames also
come with a Create event in most cases. Koni suggested sending the
MessageInfo and having the UI perform a binary search and inserting the
message in the proper position. This is optimization is left out of this
series, with a TODO left in the code.
