Remove obsolete special case for Retail mode start-up urls policy.

Remove obsolete special case for Retail mode start-up urls policy.

Chrome starts correctly with start up urls specified by policy regardless of
the session restore settings.

TEST=Enroll in Retail mode and verify that the StartUpUrls policy is respected as before.

This CL replaces the CL from Mattias
https://chromiumcodereview.appspot.com/25073002/. After some further
investigation I discovered that this workaround is not needed anymore and
completely removed this code. I will take over the change to make sure the
change is accounted for by someone while Mattias is gone.
