notmuch: move logic for dynamic folders to backend

Moves logic for creating dynamic folders from the dirlist widget to the
backend. Since dynamic folders are notmuch-specific, the notmuch backend
should be responsible for correctly setting up those folders. It does
that by sending two DirectoryInfos: the first to create the message
store, the second to fetch the directory content.

This approach also fixes a deadlock introduced by 716ade8968715
("worker: lock access to callback maps").
