Unify Pinned file link behaviour
What does this MR do and why?
This MR resolves Unify Pinned file link behaviour (#463013 - closed).
Now when you click either a link to the file or a link to the file line it will not include the pin
URL param.
The URL itself will contain that param, so if you copy it and open on a new page the file will become pinned.
This is done so that the clicks on diff files or file lines do not pin files when you refresh the page.
