Fix require-trusted-types-for

[dragonbear-os]

This is a fix for #75

I added "script" to the set of literal directive values and added a test for it.

I couldn't get the tests to run without using --runInBand which runs all the tests in a single thread which exposed that empty was getting reused across tests. So I changed the uses of empty to create a new object rather than use the one shared constant.
