Cannot override mobx actions

[ionutmiftode]

Hi,
In mobx 3.x I was able to mock actions using jest something like
myStore.myAction = jest.fn()

However after the update I receive the following error:
TypeError: Cannot assign to read only property 'myAction' of object '#<MyStore>'

it seems that in mobx 4.x actions are writable: false while in 3.x were writable: true.
I know that I can override them doing something like
Object.defineProperty(myStore, 'myAction', {value: jest.fn(), writable: true});
but it will be a pain to change it in all the 100 failing tests :).

I saw that this was fixed in #1407 but it seems that is not working for me with process.env.NODE_ENV = 'test'. Any ideas why?

mobx: 4.2.1
node: v8.9.4
