Subject: [PATCH] fix(SwingSet): Undo deviceTools behavioral change from #9153
 (#9506)

refs: #9153

## Description

This partially reverts the behavioral change from `deviceTools` from #9153.

### Security Considerations

None

### Scaling Considerations

None

### Documentation Considerations

None

### Testing Considerations

None

### Upgrade Considerations

DeviceTools are bundled into device bundles, so we want to minimize difference between code executing and code on disk.
