Do not error on any AppT in sqlMaybeSelectProcessRowDec (#406)

* Do not error on any AppT in sqlMaybeSelectProcessRowDec

No need to be this restrictive in deriveEsqueletoRecord
For example, AppT ListT _ and AppT (ConT _) _ are both fine but would
throw an error here before this change.

* Apply suggestions from code review

 synopsis:       Type-safe EDSL for SQL queries on persistent backends.
 description:    @esqueleto@ is a bare bones, type-safe EDSL for SQL queries that works with unmodified @persistent@ SQL backends.  Its language closely resembles SQL, so you don't have to learn new concepts, just new syntax, and it's fairly easy to predict the generated SQL and optimize it for your backend. Most kinds of errors committed when writing SQL are caught as compile-time errors---although it is possible to write type-checked @esqueleto@ queries that fail at runtime.
