[RFC PATCH 04/14] Not all filenames need to be converted to absolute paths

[Ethan Glasser-Camp]

_notmuch_message_ensure_filename_list converts "relative" paths, such
as those stored in Xapian until now, to "absolute" paths. However,
URLs are already absolute, and prepending the database path will just
confuse matters.
