Stop using the js-sdk's compare function (#12782)

* Stop using the js-sdk's compare function

The file is supposed to be a js-sdk internal module so we shouldn't
have been using it, and now it uses the native collator, it's completely
trivial. It was also causing Intl.Collator to be accessed at the module
scope which risked it beating the modernizr check.

* add test

* Fix tests

Move the restoreAllMocks to prevent mock leakage and also add
some custom themes to test the ordering of those.

* Move spy to the right place

* Add ANOTHER test

* Add test for integration manager ordering
