Filter shows selected enum option even when all enum options are unchecked

[asugai]

Laravel v9.41.0 Nova v4.19.3 Nova Enum Field v3.0.1

Issue: The Filter dropdown shows that an enum filter is selected even when filters have been unchecked.

Steps to reproduce:

• Check off 1 enum filter option
• See "Selected Filter Counter" change to "1" and background color change from "white" to "green"
• Uncheck the enum filter option
• See "Selected Filter Counter" stay at "1" and background color stays "green"

Expected results:

• See "Selected Filter Counter" show no counter and background color change back to "white"
