feat: make js-ipfs cli and daemon behave like go-ipfs

[dryajov]

This is needed to make js-ipfs consistent with how go-ipfs behaves - needed for ipfs/js-ipfsd-ctl#170.

@dryajov could you please add a test to this PR?

[dryajov]

will do!

EDIT: this is resolved.

I've added the test for missing Addresses.Swarm, but I'm running into a weird error. When passing my configuration with the ipfs-exec utility I get this error on daemon start:

essentially failing to deserialize Addresses.API as an array. I'm not sure what the issue might be. This has definitely left me head scratching - need to investigate some more. (it might also be the consequence of working at 5am 👅 )

[dryajov]

all issues resolved and tests added.

Thank you @dryajov :)
