* Remove unrelated checks from trusted-types-svg-script-set-href.html

This test is intended to cover setting href [1] [2] but it also
currently verifies some (currently not specified) unrelated behavior
when setting the text of the script via innerHTML. A similar test exist
in block-text-node-insertion-into-svg-script-element.html, but for a
disconnected script. This PR just move the unrelated test to
trusted-types-svg-script.html instead.
