Support parsing suite from all possible labels (#816)

* Support parsing suite and configuration from label when a task is not split in chunks

* Assert we can parse all labels to suites when checking if a group is still running on a push

* Add mochitest-browser-a11y to the list of suites

* Add a comment to remind ourselves of stopping to parse labels when the suite information will be part of the task definition
