subrepo: reset 'self.ui' to the subrepo copy of 'ui' in the hgsubrepo class

Creation of the subrepo's '_repo' object creates a new 'ui' by combining the
parent repo's 'baseui' and reading in the subrepo's hgrc file.  This simply
avoids 'self.ui' and 'self._repo.ui' pointing to different objects, which seems
like a potential source of bugs.

Git and Svn subrepos are unchanged, because they don't have their own ui, and
have always used their parent's for their configuration.
