R06006 - travel command infinite loop

The problem was caused by a test that was added to test_move() to test the
move as a regular move if it was the next step.  This case affected
boulders and closed doors, both of which are handled in later in do_move().
Remove the check.  I think this was something I thought was needed for an
intermediary version of the travel command fix, but turned out to be
detrimental in the current version.
