`flow-c1 migrate state` no longer reports errors about flow-cli

[NtTestAlert]

In my case it was a problem where FungibleToken (that is a dependency of the updated contract) had incorrect address in flow.json
That was the only problem - so re-reading .cdc files 10 times to find what might be improperly migrated was not helpful.

Sidenote: Since it is a built-in contract, and one the migrator is well aware of, it should not be required to be included in the deployments in flow.json, IMHO.

Mostly a UX problem:

• Error messages are there, but in report, and thus not obvious
• Exit code does not indicate failure
• Logs are noisy and should only contain actionable items

Additional confusion may be due to the fact that some errors - such us "cannot read contract code" do cause an error - and a fatal one at that.
But I suppose that is a cli (or flowkit) error not a state-migrator error.
