Using no_result_var in Journey's parser generator

Previously the generated parser had an intermediate local variable
`result` that really useful if you're building up a stateful object but
Journey always discards the result argument to the reduce functions.

This produces a simpler parser for anybody who actually wants to read
the thing.

Sadly, there's no real performance speedup with this change.

Only define Objetc#itself when it is not defined

Ruby 2.2 will include Kernel#itself so we don't need to define again.

Don't delegate Reflection#chain to ThroughAssociation

We shouldn't be delegating chain to ThroughAssociation since the
only place that needs to call it is `target_scope`. Instead we
can call `reflecion.chain`.

avoid testing only_path

we know that this call only wants the path returned, so lets call a
method that returns the path.
Call public methods rather than class_eval'ing
