Always add current user to autocomplete controller to support filter by "Me"

### What does this MR do?

This MR always adds the current user to the autocomplete list of users.

### Why was this MR needed?

Normally only the members from a team or the group are shown in the autocomplete list. However, this prevents a user from filtering issues belong to him/her if the user does not belong directly to either. To make this filtering more usable, we can be sure to add the current user to the list, which the JavaScript code will move to the top of the list.

Add "Confirm user" button to admin page

### What does this MR do?

This MR adds a "Confirm user" to the admin user page.

### Why was this MR needed?

There is no way for an admin to force a user confirmation. Some users create users in the API and then don't have a way to force the user into a confirmed state.

Originally, I attempted to add a link to allow the admin to resend a confirmation e-mail. But that may not be helpful because a user can be in the unconfirmed state with no `unconfirmed_email` set.
