[JSB] Fix the behaviour of publishing unavailable state interfaces when they are previously available (backport #1331)

[mergify]

Hello!

While reviewing the Example 13, I came across this situation described in the comment : ros-controls/ros2_control_demos#417 (comment)

After debugging, the resource manager properly sets the state interfaces. However, some internal variables are not properly reset, and this results in the publishing of previously available interfaces.

The proposed fix fixes the issue of properly publishing the state of the known state interfaces alone
