qdiff: refresh crashes after a commit

[Samuel Bronson]

I had opened a diff from either bzr explorer's main toolbar or the commit dialog box.
Then, after committing and pushing, I hit refresh and got this:

bzr: ERROR: exceptions.AssertionError: parent <email address hidden> has disappeared from ['<email address hidden>']

Traceback (most recent call last):

We need to reload the parent tree on refresh if the new tree is the working tree, and there was no -r arg.

I've just received a similar error when I opened a diff, made a commit, then refreshed the diff.

I'm going to bump this up based on the number of dupes.
