Need to change function deleteTraining(trainingId) in videoTrainingTrainer.vue view:

1. delete the last line:
   this.exercises = this.trainingExercises.filter(tr => tr.Id !== trainingId);
2. add this two lines at the end of function:
   this.trainingExercises = this.trainingExercises.filter(tr => tr.Id !== trainingId);
   this.loadTrainings();
