Fix unit tests (trailing spaces)

Hi.
This should fix unit tests after trailing spaces have disappeared from the source SVGs.

I guess i am [partially responsible](https://github.com/KanjiVG/kanjivg/pull/71) for the trailing white space [disappearing](https://github.com/KanjiVG/kanjivg/commit/7ff9de37f6308ae3f514db5d5be6de6f98c4b4a2)  from the source SVG. So i thought i might fix these tests.
