unittests: Run all unit tests in their own processes

Used

    sed -r -i -e '/ helpers =/ s/$/\nlocal itp = helpers.gen_itp(it)/; s/^(\s*)it\(/\1itp(/' test/unit/**/*_spec.lua

to alter all tests. Locally they all run fine now.

Reasoning:

1. General: state from one test should not affect other tests.
2. Local: travis build is failing with something which may be an output of
   garbage collector. This should prevent state of the garbage collector from
   interferring as well.
