Playing station and selected row mismatch.

[Alex Bidnyk]

If click quickly on "next station" or "previous station" button, selected row not always matches with the playing station. This represents almost always with array of stations containing more than 15 stations.
radioPlayer(_ player: FRadioPlayer, itemDidChange url: URL?) returns the selected station's url but player plays previous or before previous station.
How this can be fixed?
