Execution test cleanup (#146)

* Use current operation in execution

* No missing input stubs for deprecated fields

* Restructure result tree, attach to operation

* Clean out old execution, more type massaging

* fix warnings

* Fix introspection tests,  add debug  phase

* Fix non-typeless inline fragment tests
