Remove usage of 'remote' module from webview spec

Editor assessment

The subject states the migration: the remote module no longer used in the webview spec. The test type is right, and the absent scope is tolerable since the subject names the suite. No body is present, which is acceptable for a mechanical test migration whose source and destination the subject states, though a line on the deprecation driving it would have grounded it. The PR reference is well-formed. Imperative mood, no trailing period, compact length. A clear, self-sufficient test message that needs no diff.
