bug#18155: 24.3.92; Honor toolBar resource *before* showing frame

It is the other way around, starts with no tool bar and then adds it.

IIUC this is what Carlos mentioned.  On systems with internal toolbars,
however, we initially assume that the toolbar exists and later on remove
it if the user doesn't want it.  And the real initial height of an
internal toolbar is only known after the redisplay algorithm has passed
over it for the first time.
