Rid ourselves of unnecessary expected files

Rid ourselves of unnecessary expected files

Get rid of -expected.txt files from SVG baseline files by removing
text from the DOM. Having text elements linger classifies the tests as
'text' and requires them to have expected files. By cleaning up the
text elements before test ends, we can get rid of the expected files.
