Fix infinite loop in GridContainer layout 

I had a grid container and tried to set rect.min_height larger in the
editor; that caused an infinite loop in GridContainer::_notification
at line 118. The reason is max_index was being set to the *height* of
the row, not the *index* of the row. So later when it tried to erase
that row and try again, there was nothing to erase.
I applied the same fix to the width code.

(cherry picked from commit 561e57df13)
