Bug?	yes
New Feature?	no
Framework	Laravel
Framework version	6.x.y
Package version	9.x.y
PHP version	7.3.y

Actual Behaviour

When updating a pivot table without an id column it throws an error that the auditable_id cannot be null

SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'auditable_id' cannot be null

Expected Behaviour

Insert without auditable_id for pivot tables

Steps to Reproduce

calling $model->relationship()->updateExistingPivot($relationship_id, $data) in a controller throws the error SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'auditable_id' cannot be null

Possible Solutions

Update migration to nullableMorphs('auditable') however this results in null values being recorded for old_values. Needs to record old_values through relationship instead of by pivot id

Update migration to nullableMorphs('auditable') however this results in null values being recorded for old_values.

Instead, you can add auto-incrementing primary key and public $incrementing = true; on pivot

And how about dettaching things ? :)

Can I use laravel auditing with parameter $incrementing = false? because the id in the table uses a string type. Thanks
