[mediawiki/services/parsoid@master] TestUtils: Don't strip the content attribute

https://gerrit.wikimedia.org/r/803358

Parsoid's Sanitizer overwrites attribute values for template generated attributes which breaks templated magic word properties

I don't think the sanitizer is at fault here. We're telling it that the html represents the 'content' attribute,
https://github.com/wikimedia/parsoid/blob/master/src/Wt2Html/TT/TemplateHandler.php#L902-L903

Fair, but, there may be some tweaks to Sanitizer code nevertheless since we might end up changing the representation here. The general problem is that we don't have a good representation when more than the attribute is templated (or at least that is how our tokenizer / attribute expander sees it).
