Fix the "x of y" displayed at the top of Issuables' sidebarfix/13356-issuable-index-of-total-in-sidebar

1. We now display the index of the current issuable among all its project's
issuables, of the same type and with the same state.
2. Also, refactored a bit the Issuable helpers into a new IssuablesHelper
module.
3. Added acceptance specs for the sidebar counter.
