migrate:create feature - add --no-blank-file flag

[johngrantdev]

I was thinking about running migrate:create at the start of my build script that would be run as part of my dockerfile build (tell me if this is a bad idea). the issue is that if there are no changes to the schema it prompts.
No schema changes detected. Would you like to create a blank migration file?
This means the docker build gets stuck as it doesn't handle user input.
I would like to add a CLI argument to the migrate:create script to not create a blank migration file eg. --no-blank-file. would this we worthwhile implementing?
