Error when using the automatic turn duration

[ScribeAmanuesis]

Describe the bug
When enabling automatic turn duration and adding sockets to a node that is not a direct child of the TurnityManager, the error "Cannot call method 'is_inside_tree' on a null value" occurs

To Reproduce
Steps to reproduce the behavior:

1. Create a scene with two nodes: one that will be the TurnityManager and an other_node
2. Create a Turnity Manager with the below code:
   TurnityManager.set_serial_mode()
   .set_turn_duration(30)
   .automatically_move_on_to_the_next_turn(true)
   .start(other_node)
3. Add turnity sockets a child of the other_node without altering the settings

Expected behavior
Each node will be given the turn duration set by the Turnity Manager

Desktop (please complete the following information):

• OS: Linux Mint
• Version Godot 4.2.1

Additional context
This seems to be related to the timers on the TurnitySockets not being created
