Hide events being triggered twice when there is another step

[pedroceles]

sample code

    let tour = new Shepherd.Tour({
        classes: 'shepherd-theme-arrows',
        scrollTo: true
    })
    tour.addStep({
        text: "step1",
        attachTo: "#elementId",
        when: {
            'before-hide': () => {console.log('before-hide1')}
        }
    })
    tour.addStep({
        text: "step2",
        attachTo: "#elementId",
        when: {
            'before-hide': () => {console.log('before-hide2')}
        }
    })

'before-hide1' will be logged twice. That is because the show method for the Tour class calls this.currentStep.hide() twice when there is a next step (on lines 617 and 644).
