Unit Tests: report failed test at end of run

[crucialfelix]

On Travis we see there is that there was an error:

   �[31m 1 TESTS FAILED�[39m, �[33m7 skipped�[39m, out of 1330 (total duration: 19.0s)

Search for "?" to find failed tests.

There are 30 "?" in the 4MB log file, but none of them are the error I'm looking for.

Eventually I figured out to search for the color code �[31m

 �[31m[!]  �[39m �[1mTestEnv:test_initial_value (0.0s)�[0mERROR: Server didn't boot

At the end of the tests it should post which ones errored.

Also nice would be to have an option to only post errors, not each test.

Was it the envelope test that causes the tests to fail? I'll try and reproduce this.

@crucialfelix I had considered showing only errors - obviously this is more visible. I held off because the travis log is the ONLY place where you can see which tests actually ran... I was initially afraid of losing that data. Things have been very stable with the unit tests for a while now, so I'd have no problem making the reporting cleaner.

If the color codes are a problem, those can be avoided for the travis builds too.

Mind adding enhancement requests to https://github.com/scztt/qpm for these?
