Added extension importer remote extractor failure spec

This tests the failure case but also adds a pending failure for the success path because there is a Cloudflare HTTP 525 status error when downloading content. This definitely isn't ideal but will allow the test suite to pass until issues with the Core server are addressed.

Milestone: patch
