Related bnc#822625: Minimum height was not invalidated when rectangle changes.

5792e76cb5beb630c135f57b74f57d74dd2dc2b0 was too optimistic and did not
invalidate mnCachedMinHeight often enough.
This was resulting in a grey area below table frame when resizing it.

So, revert 5792e76cb5beb630c135f57b74f57d74dd2dc2b0
"Related bnc#822625: Cache minimum height for table cells."
and istead just use getMinimumWidth() in TableLayouter if that's all we need.
getMinimumHeight() is expensive.
