If the commit of the tag never reached master whatsdeploy is not able to figure it out.

For instance here: https://whatsdeployed.io/s-D5S

The tag 1.1.1 mozilla/PollBot@0c11c9c never reached master and whatsdeploy is having a hard time figuring out which commit of master where deployed.

It should probably look for its parent tree until it reaches commits that where on master.

This also occasionally occurs with MDN when the stage‑push branch doesn’t point to a commit on master.
