Pipeline starts before the RunOnPipelineCreate finished

[dvdlevanon-sgh]

Describe the bug
Pipeline starts before the RunOnPipelineCreate finished

To Reproduce
Steps to reproduce the behavior:

1. Create a Pipeline job, and use it as the RunOnPipelineCreate of a Multibranch Pipeline job
2. Create a new branch
3. Both the new pipeline and the PipelineCreate job run concurrently

Expected behavior
The new pipeline job should be blocked until the PipelineCreate is done

Desktop (please complete the following information):

• OS: Linux
• Browser: Opera

Additional context
From the Readme, it implies the new pipeline job should be blocked until the PipelineCreate job is done.

For example, you may need to build up a new environment when a new branch is created and this environment must be ready before the pipeline starts

The same applies for run deletion.

Hi @PhilippHomann and @dvdlevanon-sgh

Is this still happening ?
