Description
calling fit twice with different trend, first default, then trend='nc', raises exception for
no code and traceback, because copy pasting from notebooks is annoying !! (especially when I'm tired). Where's my spyder?
this is (maybe partially) a duplicate of #769 with example ic instead of trend

Research direction
Reproduce the reported case by calling fit twice with different trend values, first using the default and then trend='nc'. Read the related discussion in issue #769 and determine the expected model state after the second fit; done means the second call no longer raises the reported exception.
