Subject: manifest_xml: - Added doc and testing of unknown tags/elements.

Added this test to verify that older versions of repo can handle
"<superproject" element. Tested by adding "<iankaz" unknown element.

Tested the code with the following commands.

$ ./run_tests tests/test_manifest_xml.py
$ ./run_tests -v
