[m60 merge] [Cronet] Add null-check to avoid crashing case where no tests are run

This can happen in testAndroidTestCaseSetupProperly(), see
https://d.android.com/reference/android/test/AndroidTestCase.html#testAndroidTestCaseSetupProperly()
which is an empty test case.  Chromium avoids this but other test systems don't.
Also, remove a redundant loadLibrary call.
