Test AppCache by setting the data in TestWebServer instance.

For test case "DomStorageEnabled" should add the parameter "--test_data", as follows:
build/android/run_instrumentation_tests.py --test-apk XWalkCoreTest \
--test_data xwalkview:xwalk/test/data/device_files/ \
--verbose -I --num_retries=1 -f testDomStorageEnabledWithTwoViews
