Fix coverity : CID 19655 - Forward Null

Check the AliESDtrack pointer is not null, in the method AliAnalysisTaskCheckCascade::DoAngularCorrelation.
If null, return the function.

       AliESDtrack *lLeadingTrck = 0x0;
              lLeadingTrck =dynamic_cast<AliESDtrack*>( (InputEvent())->GetTrack( lLeadingPrimTrackIdx ) );
       if( !lLeadingTrck ) return;

Cheers,
