def empty_to_none(
    x,
    option
)

Fix empty list to None
Click option with multiple=True returns a tuple.
If option is not used, it returns an empty tuple when option is not called.
However, in fordead, most of list are expected of type list
and empty list should be None.

This function tests if list is empty and removes option from dict x,
i.e. setting the option value to None, otherwise it converts the tuple to a list updating x.

Parameters
----------
x : dict
    Click option with multiple=True
option : str
    Option name

Returns
-------
None
    The update of x is made by reference.
