Do not require tests to use .call()

Urgh, yeah, that might even be why those tests aren't passing.

Fantastic, thanks for doing this. :)

Unfortunately it looks like we might need to take a more brute force approach than this PR. Zeppelin executes most of their tests through .sol mocks that are stored in their tests folder. Those mocks are not part of the coverage measurements so they don't get swept during instrumentation.

Travis run for their latest shows the problem.

Another strategy...

• compile before instrumentation
• load the original abis
• instrument
• compile instrumented contracts
• swap original abis into instrumented artifacts
• test

Going to take a stab at this tomorrow.
