Set targetSdkVersion for our tests to be API 26.

We have been incorrectly targetting api 23 in our test apis and thus
not getting 100% correct results for newer API level devices.

Bug: 62458070
Test: ./gradlew assembleAndroidTest and then inspect the APK using
      aapt dump xmltree path/to/apk AndroidManifest.xml
