Basic Types not registried correctly if it only nested in other Object type

[ole3021]

Hi, guys, I currently fond an issue with the type registry in the stitching lib.

The bug is if some basic type(Float i tested) are not used in the root of Query type, but used only in some nested my own Object Type, then during the stitching there would have a problem of Error: No such type: Float. You can test it out or I will add some code to reproduction this bug later.

Maybe I can make some PR as well if I got time.

Looking for this bug fixed.

A small runnable reproduction here would be greatly appreciated. Thanks!

@hwillson I have created such a reproduction and linked it in #847, where it seems like some investigative work has already been done. Should we consolidate there?

mergeSchemas does not merge typedefs (!), it stitches them together by proxying. Merging can be done within makeExecutableSchema by just using an array of strings for typeDefs.

See #443 (comment)

Not sure if this addresses your issue. Please reopen with minimal reproducing repository if still relevant.
