Updated mock creation in unit tests to avoid unexpected test breaks

[ericleponner]

Description:

Changes below impact unit tests only:

1. Each call to new AdapterMock() is now followed by AdapterMock.restore()
2. AdapterMock instantiated at global or describe() level are moved to test() / it() level
3. Some unused imports have been removed
4. ContractSourceAudit test now uses a mock for solc compiler list

Related issue(s):

None

Notes for reviewer:

It's probably better to review the three commits independently.
