Wrong button order in un/hide confirmation

**Describe the bug**
The order of the buttons in the un/hide confirmation should be reversed, as it's exactly the opposite of what is intuitive.

**To Reproduce**
Steps to reproduce the behavior:
1. Un/Hide a user
2. Observe the order of the buttons

**Expected behavior**
The "do something" button should be on the right, and the "cancel" button on the left. Preferentially one of them also colored to help distinction.

The official source:

> **Place buttons where people expect them.** In general, buttons people are most likely to tap should be on the right. Cancel buttons should always be on the left.
