Prevent PCam2D Limit from resetting if an invalid path is applied

[ramokz]

Project Type

2D

Feature Description

Based on #299

If one attempts to set a limit_target through code with an invalid NodePath, then the limit_target will reset even if it has an existing valid limit target.

Ideally, it should print an error to inform the user that an invalid path was set and consequently not reset the limit size. Resetting the limit should only occur if the applied limit_target value is explicitly set to null.

Use Cases

When applying a limit target but accidentally applies an invalid NodePath reference.
