Don't display functest report for single test cases

When executing a single test case, it is not neccessary
to show duplicated information about the result of the test
case. The functest report only makes sense when running
multiple tests.
e.g. functest testcase run vping_ssh

The report is still showed when doing:
     functest testcase run all
