RandomChoiceUI : Fix handling of non-ValuePlugs

Right-clicking on (for example) a `ShaderAssignment.shader` plug in the NodeEditor was leading to the following warning :

```
ERROR : Plug menu : Traceback (most recent call last):
ERROR : File "/home/john/dev/build/gaffer-1.4/python/GafferUI/PlugValueWidget.py", line 994, in __combiner
ERROR : next( results )
ERROR : IECore.Exception: Traceback (most recent call last):

ERROR : if not Gaffer.RandomChoice.canSetup( plug ) :

ERROR : did not match C++ signature:

```
