[Android] Add test case for onReceivedErrorTest().

This patch is to add test case for onReceivedErrorTest().
Open some urls with error format, the resource client will receive
the related error. Verify the error information with the expected
result.
It's not necessary to cover the cases which is in core_test's scope. Since if xwalk core test is working, core internal test is working for sure for the same case.
