Allow Deleted Owners and Entities to be Resolved and Fix LazyLoadingViolation When Loading Owners

[rbondoc96]

Deleted Models: When records are soft deleted, the morphTo relationships return null. This allows records that have been soft deleted to still be returned.

• This affects the logger:audit-resolver command. Now, the entity relationship can be loaded even if the Entity has been deleted.
• While the owner relationship isn't loaded as part of the command, adding withTrashed to it will allow the owner to be loaded when dealing with the audit record directly.

LazyLoadingViolation Error: This error may occur when calling trackableOwnerResolver on an entity and the resulting owner model was already previously loaded (2+ entities are referring to the same owner in type and ID, see rows with IDs 3-8 below)

To fix this, every tracked model must define a getOwnerRelationshipName function that returns the name of the owner relationship to be loaded, or null if a tracked model/entity is also its owner. The return value of this function is used to load the owner relationships when the logger:audit-resolver command is ran.
