Fixed flaky CronetSampleTest#testLoadUrl test

The test was occasionally failing because of the race condition. There
are two scenarios how the test can be executed:
1. The URL can be retrieved before addTextChangedListener() is called.
   As the result onTextChanged() listener will never be called by the
   system. To address it, we call textWatcher.onTextChanged() explicitly
   at the end of the test.
2. The second scenario is when the URL is retrieved after the
   done.block() is reached. In that case the system calls
   onTextChanged() method. The problem is that the argument passed to
   the method is of type android.text.SpannableStringBuilder(). This
   object cannot be compared with the String directly. Instead,
   SpannableStringBuilder() must be converted to String and then
   compared.
