Just update the package derivation entries that need updating

Browse source 
Previously, all the entries for the branch were deleted, but not, only the
entries for the branch, that are present in the revision that was loaded will
be deleted. This is more efficient, as it avoids deleting and recreating
entries in the table that shouldn't have changed.
