2.9 minor: issues list 'Resolve' button vs. issue 'Close' button

Created by: sroth80021

This is a minor usability issue, with what I think is a simple fix.

In GitLab 2.9, there is some confusion about whether the 'Resolve' button in the Issues list is the same as the 'Close' button in the Issue itself.

Since there is no 'Close' button in the Issues List, since there is no 'Resolve' button on the Issue itself, and since I dont see a way to separately filter out resolved vs. closed issues, I presume they are equivalent.

If that's the case, then it would be nice if they had the same button text and color. It would be less confusing.

Or... If there really are two states, it would be nice if both views showed both buttons, and there was the ability to filter on closed as opposed to resolved.
