context: remove assumptions about manifest creation during _buildstatus
Previously we called self.manifest() in some cases to preload the
first manifest. This relied on the assumption that the later
_manifestmatches() call did not duplicate any work the original
self.manifest() call did. Let's remove that assumption, since it bit
me during my refactors of this area and is easy to remove.
