BugFix: draw_mpl fails with adjointed CNOT

[astralcai]

Context:
Error raised when calling draw_mpl on a circuit containing an Adjoint(CNOT). This is due to unwrap_control incorrectly considering Adjoint as a controlled operation because it has the control_wires property, and double counting the same control wires when generating default control values.

Description of the Change:
A check is added to only append more control values if the operation in focus is indeed a controlled operation.
