Capture commit message for Bitbucket Server (Stash) push events

[kotyara85]

Hi,
I saw this issue - https://discourse.drone.io/t/ci-skip-skip-ci-not-working/3914
Per Bit Bucket docs they do send the commit message - https://support.atlassian.com/bitbucket-cloud/docs/event-payloads/
Is there bandwidth for you guys to fix this?
Thanks

we used real webhook payloads when writing this library and creating our unit tests. If you look the webhook payload from the push event you will see that no commit message is provided.

if something changes, we would certainly accept a pull request that improved this behavior.
