Bug: When a user task or reward exists with the same name as a system user or task, both are shown in the assign list.

The Problem

Actual: When the user creates a task/reward from a system task/reward (copy on edit), and then goes to assign the task/reward, both the system and user task/reward are shown and can be assigned.
Expected: When a user task/reward is created from a system (or even if it has the same name) - show the user item instead in the assign views.

When a copy on edit happens of a 'good' task and it is changed to 'bad', I can see the 'good' task when assigning tasks and the 'bad' penalty when assigning the penalty
The backend will have to change to probably check if the names are the same on tasks/rewards and if so, choose to return the user items instead.
In the case of two items having the same name AND having different user_ids that are not null, then we should show both items.
The task view and reward view correctly hides the system item. However, the Task Assign View and RewardAssignView are still showing both items.

Create a test that performs a copy on edit and then makes sure only that item shows instead of the system item
Create a test that performs has 2 user items with the same name as a system item. Verify that the user items are shown, but not the system item.
Create a test where if a system and identically named user task exist that the user tasks is the only one shown in the task assign view and reward assign view.
