* Split TestPullRequest out of AddTestPullRequestTask
* Before scheduling the task, AddTestPullRequestTask stores the max
index of the repository
* When the task runs, it does not take into account pull requests that
have an index higher than the recorded max index
When AddTestPullRequestTask is called with isSync == true, it is the
direct consequence of a new commit being pushed. Forgejo knows nothing
of this new commit yet. If a PR is created later and its head
references the new commit, it will have an index that is higher and
must not be taken into account. It would be acting and triggering a
notification for a PR based on an event that happened before it
existed.
