Testlink cases for implicit alignment with unsigned numbers do not match with the actual test name. Testlink has "_u" where the test name has "Unsigned"

For instance, the testcase ngf-dfdl-2454:AlignedData_uLong-test_implicitAlignmentULong is referring to the test with name "test_implicitAlignmentUnsignedLong"

Both the title and the summary need to be updated to match the actual test name.
