manifest: have context use self.hasdir()

A couple places in context currently use "x in self._dirs" to check for the
existence of the directory, but this requires that all directories be loaded
into a dict. Calling hasdir() instead puts the work on the the manifest to
check for the existence of a directory in the most efficient manner.
