Describe the bug
When user specifies initArgs but does not specify initFunction the error message intended by the code here does not show: https://github.com/near/near-cli/blob/master/commands/dev-deploy.js#L87-L98 . It appears the logic in this code is wrong.

To Reproduce

1. Deploy and initialize the contract using initArgs but omitting initFunction, e.g.:

near deploy --accountId=mycontract01.testnet --wasmFile=res/ft_lockup.wasm --initArgs '{<add args here>}'

2. Observe that no error message is created and initialization function is not called.

Expected behavior
Error message is displayed OR new function is used by the default.
