Motor positon can be null

Here is the state of a motor when the controller was not tuned ON.

{
  srot_eh2: {
    alias: 'srot',
    callables: [
      'move',
      'wait',
      'stop',
      'rmove'
    ],
    id: 'srot_eh2',
    name: 'srot_eh2',
    online: true,
    properties: {
      acceleration: null,
      limits: [
        null,
        null
      ],
      offset: null,
      position: null,
      sign: null,
      state: [
        'UNKNOWN'
      ],
      target: null,
      tolerance: 0.0001,
      unit: 'deg',
      velocity: null
    },
    protocol: 'bliss',
    require_staff: false,
    type: 'motor'
  }
}

This is breaking the MotorTomoRotation, and breaking the full UI at the same time.

Actions

• Use this state to check every motor widget in the doc (as disconnected controller)
• Protect the main layout from a single widget break
