Regression in v5.2.0: Analog recorders never release, OpenMHz uploads stop, recorder pool exhausts #1146

Works correctly in v5.1.1
Fails in v5.2.0
Airspy Mini
Conventional SmartNet analog system
OpenMHz uploader enabled
After upgrading to 5.2.0:
recorder slots remain in "Recording" indefinitely
calls never complete
OpenMHz receives no uploads
eventually "Priority is 1 but only 0 recorders are available"
Downgrading back to 5.1.1 immediately resolves the problem.
