Before this change when you set a prompt, you have to do the following:
```rb
Pry.config.prompt = Pry::Prompt[:simple][:value]
```
The `[:value]` part was leaking implementation details and it proved to be an
unnecessary step.
With this change we can do the following:
```rb
Pry.config.prompt = Pry::Prompt[:simple]
```
`[:value]` is omitted.
I have also refactored some tests and removed irrelevant ones.
The Array API for prompt is deprecated:
`Pry.config.prompt = [proc {}, proc {}]` emits a warning now.
