Subject: [PATCH] Fix warning by not calling now-empty and deprecated retain().

```
OpenMesh/Core/Utils/PropertyManager.hh:393:16: warning: 'retain' is deprecated [-Wdeprecated-declarations]
  393 |             pm.retain();
      |                ^
OpenMesh/Core/Utils/PropertyManager.hh:325:9: note: 'retain' has been explicitly marked deprecated here
  325 |         OM_DEPRECATED("retain no longer has any effect. Instead, named properties are always retained, while unnamed ones are not.")
```
