Add issues filters reset btn

## What does this MR do?

Adds a button to the issues filter to reset all filters. I also lightly refactored a nearby method.

## Are there points in the code the reviewer needs to double check?

At the moment, the user can click the reset button even when no filters have been set. I didn't really like how it looked flashing the link on and off depending on whether a user had added a filter. I prefer having it there all the time, so the user is aware of it. But it wouldn't be difficult to hide if no filters have been set, if that's preferred.

## Why was this MR needed?

So users can reset filters when they're filtering issues.
