log += test result summary

We started to print test result summary line for a testcase run since
0153635b (Teach nxdtest to run tests locally). However it is not present
in log when nxdtest is run under master. -> Include summary lines
everywhere for uniformity, with reason similar to bd1333bb (log += title
and argv for ran testcase).
