Issue with constrained() method used after foreignIdFor(), instead of table name when $table parameter is not passed uses column name

[granitibrahimi]

When constrained() is used after foreignIdFor() then on the migration query for the constrained instead of the table name uses column name and pluralise it.

$table->foreignIdFor(User::class, 'assigned_at')->nullable()->constrained();

Query produced to add the constrain:

alter table `tasks` add constraint `tasks_assigned_at_foreign` foreign key (`assigned_at`) references `assigned_ats` (`id`);

so instead of references users it produces references assigned_ats pluralised name of the column.
