Lost schema mapping when using infix (subqueries)

[lbialy]

This is related to #520. When using infix to create subqueries mapping information defined via schema call is lost and column names are generated using given strategy, ie.: SnakeCase.

Version: new-encoding-SNAPSHOT
Module: quill-async

Given:

implicit class SubQuery[T](q: Query[T]) {
    def asSubQuery = quote(infix"$q".as[Query[T]])
}

case class User(id: Long, address: String, email: String, currentAge: Int, profileId: Long)

val users = quote {
    query[User].schema(_.columns(_.profileId -> "profileId", _.currentAge -> "currentAge")) // notice db columns are camelCase too
}

val underageUsers = quote {
    users.filter(i => i.currentAge < 18).asSubQuery
}

val underageUsersProfileIds = quote {
    underageUsers.map(u => u.profileId)
}

Expected behavior

Query generated should be:

SELECT i.profileId FROM (SELECT i.* FROM user i WHERE i.currentAge < 18) i

Actual behavior

Generated query ignores mappings:

SELECT i.profile_id, i.email FROM (SELECT i.* FROM user i WHERE i.current_age < 18) i

Workaround

Everything works fine as long as column names match results of applying selected name generation strategy to case class field names.
