Description of the bug

The merge_init_into_class option will merge the docstring of parent __init__ methods into the class docstring even if configuration does not select inherited members.

To Reproduce

• render a class which has a parent class
• set merge_init_into_class to true
• set inherited_members to false
• observe the parent docstring being merged into the class one

Full traceback

Expected behavior

The parent docstring shouldn't be merged into the class one if the parent __init__ method is not selected, or if inherited members are not picked up at all.
