remove falsy check for nulls in method parameters

[shemogumbe]

Closes microsoftgraph/msgraph-sdk-python#795

Note that

if not column is falsy even if colum exists and is zero, using if column is None will check that column is null in a better way in this case:

The generated code behavior is now adjusted from

if not body:
    raise TypeError("body cannot be null.")
request_info = self.to_patch_request_information(
        body, request_configuration
    )

To

if body is None:
    raise TypeError("body cannot be null.")
request_info = self.to_patch_request_information(
        body, request_configuration
    )

And the same applies in all areas including drive items
