MWException: restore prior render() logic

Partially revert 00bee02 by restoring the prior MWException::report()
logic. MWExceptionRenderer does not handle all of the MWException
subclasses that somehow modify the default render() behavior. Notable
among these is Flow\Exception\FlowException and its subclasses which
modify the `$wgOut` global to divert HTML output to alternate locations.

Bug: T147122
