Bluesky plan_stubs not recognized with Bluesky v1.13.0a4

[canismarko]

Expected Behavior

If I import bluesky plan stubs in my queueserver startup file, they should be available in the queueserver as plans. This was the behavior when using bluesky v1.13.0a3 and below.

Current Behavior

The plan stubs are not available.

Possible Solution

Queueserver uses inspect.isgeneratorfunction() to determine if a token corresponds to a valid plan. With bluesky v1.13.0v4, plan stubs are now wrapped and no longer pass this check.

@tacaswell's suggestion is to include a separate check to detect these wrapped plan stubs: bluesky/bluesky#1779 (comment)

Steps to Reproduce (for bugs)

1. Install Bluesky v1.13.0a4
2. Write a queuerserver startup file that imports from bluesky.plan_stubs import mv
3. Start the queueserver
4. Look at the list of available plans.

Context

We use the queueserver for executing scans at our beamline. We include a few plan stubs for making adjustments to the beamline in-line in the queue.
