fix conflict of RecyclerView's and ViewPager's lifecycles

[shpp-vsmaga]

Hello. I found one more little bug - I use your view in few places of my application and recently found that delete button don't work (visible bun not delete numbers) when PinLockView placed in fragment what placed in view pager. In this case - method of RecyclerViewAdapter onBindViewHolder called many times and all business logic (like OnClickListeners and others) placed in ViewHolder class stop to work. Definitely it's not good idea to place any business logic in ViewHolder class, it must be used only to store inflated views and no more.. Due to RecyclerView's lifecycle all business logic must be implemented in onBindViewHolder() for correct work. In my commit I moved all your business logic from constructors of ViewHolders to methods called from onBindViewHolder. Please check my changes and merge it. Thank you for your beautiful library.
