Based on the issue and pull request url, find the list of conflicting claims and display them on the accept claims page.

Solutions with better layout, and covering all the edge cases will be preferred.

Things to take care of:

1. If the target claim is for a pull request (i.e the pull request url point to a pr on github and not an issue), then only find conflicting claims which are also for a PR only. Some claims are added for suggesting features/issues, in that case the the pull request url point to an issue on github.
2. There can be terminating '/' in some urls and not others. Can be similar cases for 'http' and 'https'. Use the like sql operator to make db queries where ever required to cover such cases.
