fix #275 - quotation: add identifier method to avoid wrong type refinement inference

[fwbrasil]

Fixes #275

Problem

The quotation mechanism uses a type refinement with an annotation to store the AST. The scala compiler considers two type refinements equal if they have the same signature, which doesn't include annotations. This makes the quotation infer the wrong AST for some dynamic query compositions.

Solution

Add an identifier method to the quotation to make the type refinements different from the scala compiler's perspective.

Notes

The method name will have up to 12 characters, so we shouldn't hit any method name limit.
