In the module V2URLTests, implemented those tests from V2AddlURLTests that
were not already implemented. Removed all tests from V2AddlURLTests, as
they were redundant.

The module V2AddlURLTests is now empty and may be removed in the future if
not needed. The module V2URLTests contains all JSR 286 URL-specific
testing.
Completed implementation of additional URL tests
Fixed test case bug that was causing a null pointer exception. Added 4
additional test ResourceURL test cases to complete coverage.
