Do not use a fake row to compute completion dimension

The code in TextMetrics::completionPosAndDim is needlessly complicated.

1/ It is easier to rely directly on Text::getWord() rather than on the
   helper previousWord().

2/ Using a fake row to compute completion height is overkill. A
   simpler solution is proposed here.

No intended effect. These changes prepare the fix to ticket #11818.
