Fix for failing testsuite when using --with-xml-coverage on windows.

[jstenar]

This is necessary to get the shiningpanda testing on windows to work. Without the fix all tests fail. Using this fix I ran the tests and the results are up on:
https://jenkins.shiningpanda.com/ipython/job/ipython-windows-py27/1/

See #1428 for discussion.

If we really can get rid of this, then we no longer need the sys.platform test either.

Is this ready, then? Does it close #1428?

[takluyver]

I think it's ready (if @jstenar is happy that it works), but it doesn't close #1428. This was an issue for running the test suite itself, #1428 is a failure on a specific test.

[minrk]

okay, then.

As far as I can tell it works. Thomas is right this is a fix to get the
testsuite running.
