Improve tools/unit_tests.py (#958)

Browse source 
Checks the output more carefully. The first line of output from
js/unit_tests.ts should be something like "running 96 tests"
And the last line should be something like
"test result: ok. 96 passed; 0 failed; 0 ignored; 0 measured; 36
filtered out"
This parses those strings and make sure they align.

This will catch silent death bugs.
