title: NPE when analysing project in Eclipse (SonarQube 5.2)
body: <p>I updated from SonarQube 5.1.2 to 5.2.</p>
  
  <p>In Eclipse I start analysis with SonarQube with the latest plugin version. But a dialog pops up saying there is a NPE. The Eclipse error log displays:</p>
  
  <pre><code>java.lang.NullPointerException
      at org.sonar.ide.eclipse.wsclient.internal.SonarWSClientFacade.getUnresolvedRemoteIssuesRecursively(SonarWSClientFacade.java:170)

  </code></pre>
  
  <p>What is the problem? How can I make analysis in Eclipse work with SonarQube 5.2?</p>
