heroku bails if app name specifed in datasette publish is the same as existing app

[tlongers]

Seem that heroku does not accept an app overwrite triggered by specifying the app name using datasette publish, as below:

datasette publish heroku some.db --name "jazzy-name" 

The resulting error has the below traceback:

Creating jazzy-name... !
 ▸    Name jazzy-name is already taken
Traceback (most recent call last):

It's a solid failsafe, but does datasette publish have a way to force an overwrite?
