Closing a modal removes class `vm--block-scroll` when other modals are still open

[jxn-30]

Problem:

Having multiple Modals opened at the same time. If one of these is closed, class vm--block-scroll is removed from document.body. This is because the beforeDestroy-Method of VueJsModal does not check wether other modals are still open line 257 line 569 line 589

Version:

current (2.0.0-rc.3)

I have checked stackoverflow for solutions and 100% sure that this issue is not not related to my code.
