Fix navbar manipulation without animation

Continue of [#322](https://github.com/nolimits4web/Framework7/pull/322) 
Now it breaks with animatePages: false
updated fiddle: http://jsfiddle.net/Sl1v3r/h6ycoyps/

PS: This fiddle throws Uncaught TypeError, it seems to be another bug, just run it few times and when it is loaded without errors, randomly click digits like you did before.
