Lack of feedback when searching for similar issues in extensions when reporting an issue on an extension

[stevencl]

Issue Type: Bug

Create an issue with the issue reporter

Actual: Some extensions provide no feedback.

It's not clear if there is still a query running as there is no progress feedback.

@stevencl Good catch. Some of the extensions don't provide a GitHub url to search against (or it's incorrectly formatted), so no search is done in those cases. Would text like Unable to search for similar issues because this extension does not list a GitHub repository make sense?

I also look at two different extension properties when "Preview on GitHub" is hit to try to find the repo and only one for search, so I'll fix it so that it's more likely to find a valid repo url

I don't know if you need the full explanation, maybe 'No similar issues found' would be sufficient? Unless the user can do something with the fact that the extension doesn't list a repo?

@stevencl There's nothing the user can do in that case, so I went with your suggestion of showing 'No similar issues found'
