Don’t let people create a normal key in trial mode

You can’t properly use a normal key when your service is in trial mode.

It’s theoretically useful to create a live key in preparation for going
live. This utitily outweighs the confusion it causes for people creating
their first keys in trial mode.

We should just remove the confusing option.
