Remove redundant RunParserSyncTest calls in ImportExpressionErrors

When --harmony-dynamic-import was removed in
https://chromium-review.googlesource.com/c/v8/v8/+/2509942 it looks
like we were left with some redundant invocations of
RunParserSyncTest/RunModuleParserSyncTest in ImportExpressionErrors.
This removes them.
