Confusion in contribution guidelines regarding PR vs Issue

[Syquel]

The contribution guidelines and the default Issue template on GitHub are inconsistent and confusing in regard to whether to create a Pull Request and / or a GitHub Issue.

While the default template for new issues states

Issue or Pull Request? Create only one, not both.

the CONTRIBUTING.md in the section "Submit a Pull Request" states

For all but the most trivial of contributions, please create a ticket.

It would be great to have that consistent, because I don't know if I should create an issue for my pending pull requests and rewrite my commits to include the ticket number or not.

Thanks for bringing this to our attention @Syquel. The former is the most accurate version so please submit your PR right away.
