Fixes a bug with the merge button not showing

What does this MR do and why?

Fixes a bug where sometimes the merge button would not be visible. This, from the looks of it, is caused by the polling on the ready to merge component not running quick enough. However, instead of updating the interval there we add the properties the main components GraphQL query so that when that polling update happens the Apollo cache will update the component instead.
