Update creator_type to use getMorphClass()

[HishamM1]

Description

When creating a question cluster, question variant, interview template, or answer variant, it was expected that the creator type would match the morph type. Instead, it was returning the creator namespace as "Domain\Organization\Models\Employee" instead of simply "employee".
