MacViews: Fix LabelTest.ObscuredSurrogatePair

MacViews: Fix LabelTest.ObscuredSurrogatePair

The test sets text to an G-clef, sizes the text field to fit, then
obscures the G-clef with "*".

On Mac, a G-clef has a width of 4.36 pixels and a "*" has a width of
6.27 pixels, so when the text field becomes a "*" it is too narrow and
needs to be elided. The text field is also too small to hold an ellipsis
(13 pixels) so it just shows nothing. The test expects a "*".

Fix the test by resizing after obscuring the G-clef rather than before.
