EXTRAS-145 - Python ignores t.derive command, new name and uses DerivedRL

[tclarke]

1. Open Opticks
2. Load a data set
3. In Python scripting window type:
   t = opticks.RasterLayer()
4. In Python scripting window type:
   t.derive("DerivedRL")
   and you are prompted for a name via a Rename Raster Layer dialog
5. Input a new name then OK and Python displays:
   <opticks.RasterLayer object at 0x000000000FBAD948> (expected)
   but ignores your name and uses "DerivedRL" instead. DerivedRL displays in Session Explorer.
