[Tests] no-cycles Add failing tests for commonjs imports

[soryy708]

As part of #1056

This is expected to break the build, as at the moment "the infrastructure only registers import statements in dependencies, so cycles created by require within imported modules may not be detected.".

Coverage decreased (-2.8%) to 93.703% when pulling 78e995f on soryy708:cycles into 112a0bf on benmosher:master.

[soryy708]

Coverage decreased by adding tests? Is it accidentally counting tests/files/?

I've rebased this and merged the first commit into master.
