clang-format: [JS] wrap and indent `goog.setTestOnly` calls.

[mprobst]

Summary

While goog.setTestOnly usually appears in the imports section of a file, it is
not actually an import, and also usually doesn't take long parameters (nor
namespaces as a parameter, it's a description/message that should be wrapped).

This fixes a regression where a goog.setTestOnly call nested in a function was
not wrapped.

How is this a regression?

I would just put this under the "// These should be wrapped normally." comment that's already there.

It's testing that goog.setTestOnly does not regress. That is, we don't have any code under test that special cases setTestOnly, so it's surprising to have a test case for it, but we should have one as we're confirming a previously incorrect behaviour. Your terminology might vary.

Done though, it does make sense to keep it together with the other case above.

            Tok.Next->Next && (Tok.Next->Next->TokenText == "module" ||
                               Tok.Next->Next->TokenText == "provide" ||
