Avoid asking user to use template if `templateName` exists

[troym9731]

Even when specifying a templateName in a config file, the "Do you wanna choose a template" prompt comes up.

It seems like now that the config object is a combination of both the args and the config passed by the user, it should be fine to get rid of this prompt and just check for the existence of config.t, config.template, or config.templateName.
