Remove clutter from the user list

[smehrbrodt]

The user list looks quite cluttered with a button "Add a note" being below each user:

This change removes the text from that button (the text is still shown on a tooltip).

How to test:

Go to user manager. Without any notes attached to a user, it should look like this:

Then, add a note to a user. Before it looked like this:

After applying the patch, it should look like this (the tooltips should still work):

I think this is a bad idea. Tooltips are pretty inaccessible and I know the accessibility group is working to remove many of the tooltips currently used in the CMS. So I think this PR is taking things in the wrong direction

It looks good, but I agree with @wilsonge. If the tooltip is not shown, it is not clear what kind of functions the icons have.

When I did #6264 I had the same idea of removing the text from the buttons. But decided that it would be bad for accessibility

On the basis of the above comments I'm going to close this PR

Why? I don't understand the problem with accessiblity. If there is a problem, we should use the aria-label attribute, not just show a label everywhere

@smehrbrodt if you have a problem with coordination and you can't control the mouse pointer exactly over the button then you are not able to get the info.
