Viewport does not update when deleting Hidden Display Layer containing USD Objects

[sbissonnette]

Describe the bug
When we delete a Display Layer with its Visibility flag set to OFF, all USD Objects that were in it won't reappear in the Viewport.

Steps to reproduce

1. Create an Empty Stage
2. Create Sphere Prim
3. Create Display Layer with the Sphere
4. Set Display Layer Visibility to OFF
5. Delete Display Layer
6. Notice the issue (Sphere isn't visible in viewport)

Expected behavior
All USD Objects that were in the deleted Display Layer should be back visible in the Viewport.

Workaround
I currently found nothing. We need to re-open the scene.

Code Sample to create the scene

import mayaUsd
import maya.cmds as cmds
from pxr import UsdGeom

# Create Stage node
stage_node = cmds.createNode('mayaUsdProxyShape', skipSelect=True, name='stageShape1')
stage_node = cmds.ls(stage_node, long=True)[0]

# Create USD Sphere
stage = mayaUsd.ufe.getStage(stage_node)
xformPrim = UsdGeom.Xform.Define(stage, '/hello')
sphere_prim = UsdGeom.Sphere.Define(stage, '/hello/world')

# Create DisplayLayer with Sphere
dag_node = '{},{}'.format(stage_node, sphere_prim.GetPath().pathString)
cmds.select(dag_node)
cmds.createDisplayLayer(name='USDSphere')
