When a shop changed, the Places overlay does not delete the source:opening_hours tag from the object.
The source:opening_hours is a documented tag: https://wiki.openstreetmap.org/wiki/Key:source:opening_hours

How to Reproduce

1. Find a shop that has at least those tags: name, opening_hours, source:opening_hours
2. Using the Places overlay, change the name of the shop and confirm that it is a new place
3. Observe that name is changed, opening_hours is deleted and source:opening_hours remains

Expected Behavior
The tag source:opening_hours should be deleted.
