console: invalid migration when changing column default value

[beerose]

Steps to reproduce:

1. Crate table.
2. Set default for a column.
   Generated migrations will be okay at this point:

up
- args:
  cascade: false
  read_only: false
  sql: ALTER TABLE ONLY "public"."user" ALTER COLUMN "info" SET DEFAULT 'some info';
type: run_sql

down
- args:
  cascade: false
  read_only: false
  sql: ALTER TABLE ONLY "public"."user" ALTER COLUMN "info" DROP DEFAULT;
type: run_sql

3. Change the default value.
   Up migration will be correct:

- args:
    cascade: false
    read_only: false
    sql: ALTER TABLE ONLY "public"."user" ALTER COLUMN "info" SET DEFAULT 'new info';
  type: run_sql

But the down migration would have the incorrect syntax (''some info'::text' part):

- args:
    cascade: false
    read_only: false
    sql: ALTER TABLE ONLY "public"."user" ALTER COLUMN "info" SET DEFAULT ''some info'::text';
  type: run_sql

this should be again
sql: ALTER TABLE ONLY "public"."user" ALTER COLUMN "info" SET DEFAULT 'some info';
right?
