smart-contract tests fail subsequent runs

[MantisClone]

The smart-contract tests pass on the first run but fail on subsequent runs. This is because they don't reset the aggregator state on the ChainlinkConversionPath contract.

2nd Run:

  1 failing

  1) contract: ChainlinkConversionPath
       admin tasks
         can updateAggregator and updateAggregatorsList:
