Fix issue: clear selection not shown after the select control has been populated with data after initialization. On initialization, if there are no options, the clear selection X button is not shown. However, once options are set, for example, as a result of an asynchronous call to the server to get the option data, the test is not reperformed and therefore the clear selection button is not enabled. The fix checks for option data and enables the clear selection button, if originally enabled in the settings, after the call to set new data. This fix will also remove the clear selection button if the control is updated with empty data.
