fix #21797: IOOBE in ImageryProvidersPanel$ImageryDefaultLayerTableModel.getValueAt

This was caused by a race condition in newer JVM's when the cancel button is
pressed. This splits out the code forcing a refresh of the tables into its own
method, and calls that method in the worker thread after we finish
redownloading the imagery list.
