Remove unneeded test

Correct me if I am wrong, but since wrong is false (defined at [line 100](https://github.com/osmandapp/OsmAnd-core/blob/master/OsmAnd-java/src/net/osmand/plus/voice/AbstractPrologCommandPlayer.java#L100)) it's not necessary to test for it at [line 109](https://github.com/osmandapp/OsmAnd-core/blob/master/OsmAnd-java/src/net/osmand/plus/voice/AbstractPrologCommandPlayer.java#L109) (since it will only be true after the if).
