largefiles: drop the override for 'fetch'

The fetch extension has been calling cmdutil.bailifchanged() since a014fdc97154,
so this is redundant.  Add test coverage to prevent regression.  It doesn't look
like there is any testing for fetch with largefiles.

# Read the output of a "svn log --xml" command on stdin, parse it and
# print a subset of attributes common to all svn versions tested by
# hg.
