Dispose: delete pre-created folders when the template does not exist

[peterroe]

Describe the feature

When trying to giget a template that doesn't exist,

$ giget gh:unjs/empty

the folder ends up being created:

|- unjs-empty

Should we make the behavior of giget and git consistent, Clear the pre-created folder when the template doesn't exist ?
