* Update test confirmation text in PR template
We only ask users to check when adding new tests, but
some PRs only modify existing tests. Also added
instructions to mark with an "x" for checking off items.
- Remove sign CLA since CI already shows unsigned CLAs
- Remove all tests must pass CI since we have to check each on a case by
case basis anyways
- Update example to include linking to the current repo using number
sign (ie. #49 in addition to org/repo#49)
