Failed Reference when Pushing New Branch

[ALEEF02]

Describe the bug
When the action is run on a new branch push, the run fails. This is because the script cannot find the previous reference and uses 0s.

To Reproduce
Create a new branch and push a DrawIO file on that branch.

Expected behavior
Should reference the last commit from the previous branch

Currently, the search for the previous reference is not possible based on the branches.

I have opened #37 to try to improve this behavior in the future.
