Fixes ABI alias metadata types.

[esdrubal]

Description

Before this push, using an alias in a contract would produce an ABI with two distinct metadata types for tuples: one for (_,_) and another for (u64,u64).

With this change, aliases are bypassed and we only produce metadata for the string type of the inner alias type. If alias is (u64, u64) we will produce a metadatatype for (_,_).

Fixes #6488
