title: Manifest Merger failed - InstrumentationTestRunner
body: <p>I have just recently migrated my library project from Eclipse to Android Studio 1.1.0. Every time i try to run test or clean the project, i get following error:</p>
  
  <pre><code>Error:(15, 22) Execution failed for task ':app:processDebugAndroidTestManifest'.
      &gt; java.lang.RuntimeException: Manifest merger failed : Attribute instrumentation#android.test.InstrumentationTestRunner@label value=(Tests for com.dummyname.lib) from manifestMerger3662930390325374798.xml:15:22
          is also present at debug:16:9 value=(Dummyname Tests)
          Suggestion: add 'tools:replace="android:label"' to &lt;instrumentation&gt; element at manifestMerger3662930390325374798.xml:11:5 to override
  </code></pre>
  
  <p>I've put 'tools:replace="android:label"' into my AndroidManifest.xml but nothing happened. Any ideas on how to deal with this?</p>
