Avoid outputting the assert message twice in non-GUI code.

As we always log the assert message in ::ShowAssertDialog() itself there is no
need to log it again in wxAppTraitsBase::ShowAssertDialog().

Also show the "please wait while generating stack trace information" in
wxAppTraitsBase::GetAssertStackTrace() itself instead of doing it in both
places which call it.
