Entity operations should be cached by url

Problem/Motivation

Recently, an entity operations field was introduced for search api based views.

The views row caching doesn't take the URL into account. That means, the operations link including the destination query parameter, is generated just once.
So if you are using facets, for example, to drill down the search results and then using an entity operation you come back to another page from where you left the view.

Proposed resolution

Add the url as cache context.
