_pytest.compat.get_real_func is unaware of getattr-ish objects like mock.call

[RonnyPfannschmidt]

this would break on things like the mock.call object, there should be an iteration limit

i propose using something like

for _ in range(1000):
  new_func = getattr(func, '__wrapped__', None)
  if new_func is None:
    break
  else:
    func = new_func
else:
  raise ValueError("unwrap failed to find a end")

all tho i presume we can pick a much lower iteration count
