Try #2: (Bug 50835) Dont nowiki escape already escaped tpl params

* The previous fix (ee5acb50) didn't correctly tackle all instances
  of nowiki showing up in template params. It assumed the tokenizer
  to emit a single token for content between <nowiki> and </nowiki>

  Not true for {{echo|<nowiki>&apos; &apos;</nowiki>}} for example

* Fixed the bug and added a new test.

* Unrelated changes:
  - Some regexp escaping to stop jshint whining.
  - Moved a test to a different section where it belongs.
  - Regenerated selser changes for recently added tests.
  - Updated blacklist based on regenerated selser changes.
