Title: Bug: TextSymbolizer.horizontal-alignment - always left when using expressions

I found a bug, expressions in TextSymbolizer horizontal-alignment do not work, they will always be aligned to the left. I'm using the current master branch (commit 8b2243336b53a94494c461cf016e2ffa1ed05c20).

This pictures are created when I run the test:
