Keep GDScript functions in stack while yielding

Browse source 
This prevents GDScript functions from leaving the stack too soon when
they are resuming from yield, allowing the ones expecting it to finish
to know the caller.

Helps debugging cases when you use:
`yield(function_which_yields(), "completed")`
since now it shows the call that resumed that function.
