test: removes all unnecessary page.waitForURL methods (#11412)

Removes all unnecessary `page.waitForURL` methods within e2e tests.
These are unneeded when following a `page.goto` call because the
subsequent page load is already being awaited.

It is only a requirement when:

- Clicking a link and expecting navigation
- Expecting a redirect after a route change
- Waiting for a change in search params
