Coverage only runs for last specified test

[bramp]

I execute qunit like so:

    $(NODE_MODULES)/qunit \
        --cov \
        --timeout 60000 \
        -d Random:$(BOWER_COMPONENTS)/random/lib/random.js \
        -c Prob:dist/prob-min.js \
        -t tests/*-tests.js

I have two files that match "tests/*-tests.js", "tests/prob-tests.js tests/import-tests.js".

I noticed when I added the 2nd file my tests started to run a lot quicker. I figured out that coverage was not being run on whichever test file was first, and only on the 2nd one. I can observe this due to the speed the test executes as (as coverage slows down the execute of tests/prob-tests.js a lot), in addition the lcov-report clearly seems to only show coverage from the 2nd test.

I noticed this on my https://github.com/bramp/prob.js project.

any chance you could provide a failing test?
