Remove .internal override from untrusted URL tests

Adding `.internal` to a test file override prevents it from being tested
in build mode. The best practice is to instead gate the test based on
whether the feature is enabled.

Ideally we'd use the `@gate` pragma in these tests, but the `itRenders`
test helpers don't support that.
