fix: nested array from tuple and schema generation

[saihaj]

Adds bunch of debug logs that in future should make debugging generation issues easier.

1. Main thing is that today any nested arrays were unable to be processed. With this PR we can validate any nested array in GraphQL Schema.
2. We generate types from tuple and we want all those generated arrays to be Non-Nullable to avoid any user confusion

closes #1399
