Updated flow types

[johanneslumpe]

toOrderedSet and toOrderedMap were updated in the typescript definitions, but not the flow ones.

@leebyron The changes in the above referenced PR caused the flow checks for draft-js to break. The changes here fix some of these. But there are more issues cropping up which have to do with incompatible types. Locally I tried copying over all the methods (minus the update methods) from the Map to the OrderedMap type and update the return values. Is this the correct way to deal with this?

If so, I can update this PR to include those changes as well!

I'm going to accept the PR to switch Draft to ~3.7.4 to sidestep this. Would be awesome to be able to switch it back soon.

@johanneslumpe This repo is not actively maintained as far as I can see. I created a PR in flow-typed to add flow definitions for immutable there.

My fork is here. Feel free to submit a PR with your changes there.

So #878 refactored the flow types and also added tests for them. Would you mind updating this PR to merge those changes in, and also add a test that catches this? Thanks!

@lacker I just submitted a PR that address this issue along with OrderedMap / OrderedSet typing issues: #1027

OK, I am going to close this one in favor of 1027.
