Seigo Nonaka c3b9f7dadd Fix test utilities ...

This fixes following three memory leaks in test utilities.
There is no problem in production code and this CL doesn't affect
any production behaviors.

- SkTypeface leaks due to forget calling SkSafeUnref in dtor.
- MinikinFontForTest leaks during constructing FontCollection.
- FontCollection leaks due to unnecessary AddRef.
