fix: fetch reference types for JS files (#4652)

Fixes #4000 and fixes #4476. Now always tries to fetch reference types
for JS files. Does not throw if it fails, since Typescript compiler will
complain if the file is not there(it will try to fetch it again first)
and people who just use JS should not be bothered by this error.

Not sure about my test, it passes and catches the bug but maybe there is
a better way to express it.
