`DeleteAll` finisher ignores the inner join query mod

[Dot-H]

What version of SQLBoiler are you using (sqlboiler --version)?

After #702 : 3.7.0

What is your database and version (eg. Postgresql 10)

MySQL 8.0.19

If this happened at runtime what code produced the issue? (if not applicable leave blank)

models: unable to delete all from pilots: Error 1054: Unknown column 'jets.pilot_id' in 'where clause

Please provide a relevant database schema so we can replicate your issue (Provided you are comfortable sharing this)

I used the example database schema to reproduce.

Further information. What did you do, what did you expect?

What I did

	// Should have something like:
	// DELETE `pilots` FROM `pilots`
	// INNER JOIN `jets`
	// WHERE `jets`.`pilot_id`=`pilots`.`id` AND (`pilots`.`name`=?)
	nbdel, pilotE := models.Pilots(
		qm.InnerJoin(models.TableNames.Jets),
		qm.Where(
			models.TableNames.Jets + "." + models.JetColumns.PilotID + "=" +
			models.TableNames.Pilots + "." + models.PilotColumns.ID,
		),
		qm.Expr(
			models.PilotWhere.Name.EQ(pilotName),
		),
	).DeleteAll(context.Background(), globalDB)

Debug output (boil.DebugMode = true):

DELETE FROM `pilots` WHERE jets.pilot_id=pilots.id AND (`pilots`.`name` = ?);

• The above code ignore the INNER JOIN. I expected it to be present.
• There is should be "pilots" before the FROM otherwise there would be a syntax error when adding the INNER JOIN.

I know the above query does not make a lot of sense. But the inner join in a delete have use cases: "Delete all pilots which have a common jet with the pilot currently being deleted"

This seems to be a mysql-specific feature request. Looking at postgres' delete syntax it has a different way of pulling in other columns.

Probably not going to do this as it lacks utility for postgresql. Though any non-breaking pull-request to fix this would probably not be turned down if it wasn't crazy :D
