Fix for the PR title not being pulled through to the Release title, thanks to @darryldaniel

- Fixed an issue with inconsistent handling by the JavaScript URL constructor would sometimes cause the release link to be off of the org and not the project (so it would be invalid)
- Fixed a similar issue which would cause querying for tags to fail

Periodically polls the PR information to update the Create Release link as necessary (latest tag, updated title / description)
