remove need to swap dids for canisters with deploy arguments

[letmejustputthishere]

currently when a canister is referencing another canister using the "canister:name_of_other_canister" syntax, and that canister has deploy arguments, we first have to deploy the canister with a did file that contains the deploy arguments, then swap the did file to a version that does not contain the deploy arguments, until we finally can deploy the canister the references the canister with the deploy arguments.

that's pretty cumbersome and involves manual intervention or additional scripts that have to be written to automatically change the reference to the did file.

ideally dfx automagically removes the deploy arguments from the did when the referencing canister is deployed.
