Autoformat all the *Test.java files under javascript/jscomp

This will certainly have hurt the readability of some test cases where
our preferred `lines()` call with a trailing comment to force
one-argument-per-line is not already in use.

But, this will eliminate the very annoying case where autoformatting
keeps forcing formatting changes that obscure the meaningful ones.
