[ProfileAPI] Cannot delete a profile which doesn't have DeviceId

Description

1.Create a profile without DeviceIds
2. Using API to delete profile based on DeviceId:

DELETE: /api/v1.0/profiles/{{scope}}/{{profileId}}

-> It returns 200 OK with message: Successfully removed data for profile item profileId
3. Get profile in the previous step

• Expected: The profile is deleted
• Actual: The profile is not deleted, it is displayed in the list
  Note that: The bug doesn't occur when I add email of the profile in blacklist, then clear user data of the profile.
