Check if baton FuncRef is valid before calling call_funcv()

Browse source 
Often when closing a terminal in the terminal panel the error message
'Condition "!obj" is true.' would be printed to console.

This was due to the call_funcv() method being called on an invalid
FuncRef instance (invalid because it had already been deleted or queued
for delection).

Now we check the instance is valid before calling the method.
