REGRESSION(r269957): Empty font names passed to canvas2d cause all text routines to crash https://bugs.webkit.org/show_bug.cgi?id=222402 <rdar://problem/72621268> Reviewed by Darin Adler and Chris Lord. Source/WebCore: It looks like it was simply an oversight from that patch. If the font name is empty, CanvasRenderingContext2D::setFont() will set the font object to one that doesn't have its internal FontCascadeFonts pointer set.

This test makes sure that canvas2d's text functions don't crash when passed unexpected font strings. The test passes if there is no crash.
