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

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.
