Running a unit test with code coverage enabled does not generate data in coverage.csv

[roelrz]

The command line option -c or --coverage enables code coverage for a unit test.

However, no actually data is written to the coverage.csv file.

Files worth investigating:

• lib/testrun.js [defineProperties()]
• lib/executor.js [shutdown()]
• lib/coverage.js [writeSummary()]

Yeah, I was surprised by this myself to find that the generated coverage.csv contained only headings and no data.

@roelrz @zackthehuman I've found the root of this issue; we were using @venus-include instead of @venus-code to include the files that we wanted to record coverage for.
