resulttool/manualexecution: To output right test case id
We found that manualexecution does not capture test suite values
correctly if there are more than one test suite in test cases.
After verification has made we found out we should retrieved
full test cases value <test_module.test_suite.test_case> from
oeqa/manual/ json file rather than split it them into new
variables test_suite and test_cases.
