title: Changing the AzureDevOps trigger doesn't work (from build to build pipeline)
body: <p>I'm trying to trigger the build of pipeline B based on the build of pipeline A. This works, and I tested this on a feature branch before changing it to master. However, when I change the branch to master, it does NOT trigger on master, but still triggers on the feature branch.</p>
  <p>I added the following to trigger pipeline B:</p>
  <pre><code>resources:
    pipelines:
    - pipeline: test1
      source: test1
      branch: master
      project: project1
      trigger:
        branches:
        - master
        stages: 
          - buildPackageMaster
  </code></pre>
  <p>Previously, for testing purposes it was configured for a feature branch, as follows:</p>
  <pre><code>resources:
    pipelines:
    - pipeline: test1
      source: test1
      branch: feature/DATA-24843
      project: project1
      trigger:
        branches:
        - feature/DATA-24843
        stages: 
          - buildPackageNonMaster
  </code></pre>
  <p>But it doesn't pick up the change I made. So it still triggers on a change in feature/DATA-24843, but not from master. Any ideas on why this happens and how I can fix it?</p>
