UNKNOWN_DUT test record is output when sig-int is sent at start prompt

See the following files output when running all the things and doing sig int at the prompt. Expectation would be to not get a test record output correct?

UNKNOWN_DUT.MyTest.1528518533178.pickle
UNKNOWN_DUT.MyTest.1528518533178.json

~/openhtf/examples$ python all_the_things.py
Enter a DUT ID in order to start the test.
--> ^C
