Issue description

When using .onUpdate, the SQL is not being composed correctly.

Expected Behavior

INSERT INTO "product_category" AS "ProductCategory"("_id", "name") VALUES ($1, $2), ... ON CONFLICT ( "_id" ) DO UPDATE SET "name" = EXCLUDED."name" WHERE ("ProductCategory"."name" IS DISTINCT FROM EXCLUDED."name") RETURNING "id"

Actual Behavior

QueryFailedError: invalid reference to FROM-clause entry for table "product_category"

INSERT INTO "product_category" AS "ProductCategory"("_id", "name") VALUES ($1, $2), ... ON CONFLICT ( "_id" ) DO UPDATE SET "name" = EXCLUDED."name" WHERE ("product_category"."name" IS DISTINCT FROM EXCLUDED."name") RETURNING "id"

Steps to reproduce

await this.productCategoryRepo
    .createQueryBuilder()
    .insert()
    .values(
        categories.map((category) => ({
            _id: category.id,
            name: category.name,
        })),
    )
    .orUpdate(
        ['name'],
        ['_id'],
        {
            skipUpdateIfNoValuesChanged: true,
        }
    )
    .execute();
