fix: adding connectionID to portID generator fn

[seantking]

Description

Adding the connection sequence to the NewControllerPortID helper fn.

This change makes it possible for the API to be used in a way whereby a dev using InitInterchainAccount can use the same owner address for multiple host chains (represented by connection).

Alternatively, we could not make this change and ask the ica-auth module dev to create a unique owner-id per account and manage this whichever way they choose. In that case we simply need to update documentation and provide an example.
