Remove devtools Schema introspection from view

About

We want devtools to give us all information about what is going on with the client, but the introspection query triggered by devtools is an annoyance.

Let's hide that specific query (while still showing any introspection queries not sourced from devtools).

Note

• If the introspection query fails for some reason, the user won't be able to know this or see why - it would be cool if we could find a way to present this to the user.

@andyrichardson About the note, I have some error states on the Schema view if introspection fails so that should take care of this!

That's perfect!!
