feat: report all passing & failing contract checks

[anna-carroll]

Motivation

Right now, contract deploy checks throw an error and stop when the first check fails.

This makes it difficult to take stock of ALL of the checks which are not passing, and often, the errors thrown are not very informative.

Solution

• run all of the contract tests (even if some of them fail; don't throw an error and halt the process)
• push test results to an object
• separate passing tests & failing tests
• print the object at the end of the process
• throw an error if any failing tests are present
