manifest: call m1.load and m2.load before writing a subtree As part of refactoring the manifest, certain test cases started failing because writesubtrees was called with p1 and p2 manifests that had not been loaded (so accessing m1._dirs resulted in an empty set). Let's call _load on these before attempting to access _dirs. This was caught by tests when future patches were applied.
