Looks good. Can you rebase this quickly? |

When two platform variants of a single module ID change at the same time (ex. often happening after a far rebase), jest was loosing one of them, depending on the ordering of the change events. This is because it doesn't care about platform variants and deletes the whole module metadata every time. This is probably here for historical reasons, from before the introduction of platform extensions, and wasn't unit-tested.
This changeset adds a test and the corresponding fix for this behaviour. I wrote the test first and could see it failing if the correct fix is not added as well.
