tr-summary: keep a weakref to the unfiltered repository
Repoview can have a different life cycle, causing issue in some corner
cases. The particular instance that revealed this comes from localpeer. The
localpeer hold a reference to the unfiltered repository, but calling 'local()'
will create an on-demand 'visible' repoview. That repoview can be garbaged
collected any time. Here is a simplified step by step reproduction::
1) tr = peer.local().transaction('foo')
2) tr.close()
After (1), the repoview object is garbage collected, so weakref used in (2)
point to nothing.
Thanks to Sean Farley for helping raising and debugging this issue.
