Fixes the intermittent test failure experienced by #232 #231
It think this may have been introduced in #172. In my fork, this is the earliest failure I see in the commit history, but it differs on every fork I checked.
For whatever reason, occasionally this test will encounter an issue where

new'ing a contract deployment collides with an existing contract deployment. This is probably a race condition in the nonce mgmt or test network setup/teardown given the error message:CreateCollisionindicates contract code exists at the desired address. At first, this seemed like it was an issue in the deterministic deployment. I rotated the salt values of each one without any change.Refactoring the InvalidImplementation to deploy during test setup fixed the issue.
