Add attributes to the Parsoid-only tests.

Needed to fix these up in order to get them running right when the Parsoid
test-runner begins to let through more attributes.

Several tests are make wt2html/wt2wt only because they involve templates
which we can't convert from html2wt without additional information.
The "SOL-sensitive wikitext tokens" test was previously wrong: the PHP
preprocessor generates lists from the template content.  Updated it to
the proper results while adding attributes, although it will currently
fail until we either fix the native Parsoid preprocessor or tweak our
parserTests to use the PHP preprocessor.
