RFR: 8328667: [Testbug] Enable ignored Spinner unit tests

Thu Mar 21 07:22:32 UTC 2024

Enabled a test in `SpinnerTest` class.
Added comment to the editing test, why it can not be enabled. When Spinner value is set using `getEditor` `setText` method, the listener added to the spinner is not invoked. There is no bug for this issue. I'm not sure about the expectation in this case.
Other set of tests which are ignored are `LocalTimeSpinnerValueFactory` tests. Since these tests are unstable and fail only at certain time of the day, not enabling this test as well.
