Use deployer as a fallback to call approveOperatorContract

For ropsten we expect that approveOperatorContract will be called by the
account that is defined as keepRegistryKeeper in the hardhat config,
but for hardhat local network and for usage in external project it's
just fine to assume the deployer will be used as a fallback, so the
external project doesn't have to define keepRegistryKeeper.

This is a continuation of #92
