Title: Fixed a regression caused by a641a21fa146542585e15e3ea3a7f133bee31c8d that makes a long, top aligned label sometimes not draw the last line

The bug can be triggered by having the alignment being
TTTAttributedLabelVerticalAlignmentTop and lineHeightMultiple being
greater than 1 (1.03, for example). Matt's old code handled this well,
but a641a21fa146542585e15e3ea3a7f133bee31c8d broke it.
