SnackbarProvider: prop type TransitionComponent is invalid

[frafajec]

Expected Behavior

No error should occur on <SnackbarProvider /> render.

Current Behavior

Error is thrown as soon as SnackbarProvider is rendered, complaining about the prop type definition. (note: functionality is not affected, just console spam)

Steps to Reproduce

I didn't manage to repro this on sandbox, Im not sure why. Build is completely fine, but this is output in the console:

Warning: Failed prop type: SnackbarProvider: prop type `TransitionComponent` is invalid; it must be a function, usually from the `prop-types` package, but received `undefined`.

I debugged a bit and found that TransitionComponent propType is: TransitionComponent: undefined, meaning propType passed doesn't exist.

Solution?

I changed in node_modules prop type for TransitionComponent to func, which then supplied propType and no complains from then on. Solution here: #130

This issue is actually happening on the demo link that's on the README page.

I took a closer look, and found out what the root-cause is.
It looks like 15.6.2 prop-types version doesn't support elementType, and package.json still uses 15.6.2.
But the package-lock.json is using 15.7.2 which doesn't cause this issue.

So, if you use "yarn" to build your project, it will read in package.json and install 15.6.2 version of prop-types which doesn't support elementType.

I think we just need to update the package.json to have proper version as well. I wonder how the package.json and package-lock.json got out of sync.
