Empty Select when Column("_") is used

[Janther]

When I already have a model in memory and I want to load a relation of that model I do something like this:

db.Model(&user).
    Column("_").
    WherePK().
    Relation("Roles").
    Select()

This will generate an extra very silly and unneeded empty query.

SELECT  FROM "users" AS "user" WHERE "user"."id" = 6

I tend to load the info all at once but sometimes is way too complicated.

I understand that this is the desired result of Column("_") but this makes sense on "has one" relations where there will be a JOIN and the other tables columns will be selected. On the other relations looks like a bug.
