[wptrunner] Clean up stale harness-level 'ERROR' expectations

This change removes spurious harness-level 'ERROR' expectations caused
by test URL validation in wptrunner that was too strict [1]. This
reclaims coverage for these tests, erring on the side of removing too
many expectations, which the WPT autoroller can regenerate.

This change was mechanically generated in two pieces:
* git restore --source=c69a9719~1 '*.ini' - The autroller added these due
  to a bug in web-platform-tests/wpt#39007.
* Run a cleanup script [2] that removes the original 'ERROR's (e.g.,
  'undefinedundefinedundefined').

See [3] for what these '.ini' files are.
