Generic/FunctionCallArgumentSpacing: fix regression for new parent

Related to 3546 which fixed an inconsistency after 3484.

The change of the tokenization from `T_STRING` to `T_PARENT` for the `parent` keyword in `new parent` caused a regression in the `Generic.Functions.FunctionCallArgumentSpacing` sniff.

Fixed now.

Includes unit tests.
