remove qunit/v1 references in tests (#40866)

references to `v1` in the test files work on Definitely Typed but don't
reflect real usage, which specifies versions using package.json.

The fix in this case is easy -- switch to current version of qunit. This
required some test changes to jquery.bbq, but they were all renames,
essentially.
