Callback always called twice when providing prompt_fn and callback to InteractiveOption

[janssenhenning]

Describe the bug

Using both the prompt_fn and callback arguments in the InteractiveOption leads to unexpected additional calls of the callback function.

Steps to reproduce

from aiida.cmdline.params.options.interactive import InteractiveOption

def prompt_callback(ctx):
    print('prompt callback')
    return True

def callback(ctx, param, value):
    print('callback')

@click.command('test')
@click.option('--label',
              cls=InteractiveOption,
              prompt='Label',
              prompt_fn=prompt_callback,
              callback=callback)
def cmd_test(label):
    print(label)

Output:

prompt callback
Info: enter "?" for help
Info: enter "!" to ignore the default and set no value
Label: test
callback
callback
test

Expected behavior

The callback should be called only once after the sucessfull prompt

prompt callback
Info: enter "?" for help
Info: enter "!" to ignore the default and set no value
Label: test
callback
test
