Set cache=False option on all FilterHook instances used on object methods

[rafalp]

FilterHook instance called with object's method as action will save this instance in its cache, producing a memory leak and breaking hooks next calls if used object is not singleton.

Example:

class MyClass:
    def do_something(self):
        hook(self.do_something_action)

    def do_something_action(self):
        ...

If MyClass is not singleton, first instance's do_something_action method instance will be cached on hook instance and used in all future calls.
