title: Bitbucket hook build from branch does not work for Jenkins
body: <p>I have Jenkins with a job for SonarQube analysis, with the following value:</p>
  
  <pre><code>GIT SSH URL - set correctly
  Branch Specifier - "**"
  </code></pre>
  
  <p>In Bitbucket, I have given the following value:</p>
  
  <pre><code>Jenkins URL - http://101.101.101.101:8080/Jenkins
  Skip SSL Certificate - Enabled
  Omit SHA1 Hash Code - Unchecked
  Omit Branch Name - Unchecked
  Omit the Trigger Build Button - Unchecked
  Advanced Config:
  Committers to Ignore - Blank
  Branch Options - Build All selected and Blank field
  </code></pre>
  
  <p><strong>I want Bitbucket to trigger Jenkins only if code is merged (from a pull request) to particular branch.</strong></p>
  
  <p>I tried the following settings in Bitbucket:</p>
  
  <pre><code>Branch Options - Build From selected and "release/Integeration" in the field
  </code></pre>
  
  <p>Still changes to every branch is triggered.</p>
  
  <p>I tried this in Bitbucket:</p>
  
  <pre><code>Branch Options - Build From selected and "ref/heads/release/Integeration" in the field
  </code></pre>
  
  <p>Now nothing gets triggered.</p>
