Wait for settings menu animation on users page

[phil-davis]

Part of issue https://github.com/owncloud/core/issues/34689

There are webUI tests on the users page that adjust the settings and then check that columns are visible or not, or try to enter password or email address etc. These tests have become intermittently unreliable. I think faster test systems will see this timing issue more often.

After investigation, I realized that the settings menu on the users page opens with an animation. The observed behavior is that if the test tries to click a setting checkbox before the animation is finished, then the click is not effective, but does not return and error.

However, as soon as the test clicks to open the settings menu, isVisible() on the settings menu returns true - although the menu might still be animating itself.

Basically it's a PITA. We could design some sort of JS query to send in a loop to try and see if the menu is still in an "animating" state. Or we can repeatedly query the size/position of the menu div and wait until it has been "steady" for "a while". They are the 2 common approaches that others take to try and cope with waiting for animations. That will all take time to work out the gory details.

At the moment this is causing significant percentages of "random" test fails, which is not "a good thing". So put in a 1 second sleep (which I hate to do)

On my local development system this scenario would fail about 25% of the time:

make test-acceptance-webui BEHAT_FEATURE=tests/acceptance/features/webUIManageUsersGroups/addUsers.feature:74

Watching the browser, I could see that I did not successfully click off "Set password for new users". And so the password box stayed and the email box was not displayed for creating a new user.

And so the test fails with:

    Examples:
      | username | comment          |
      | guiusr1  | simple user-name |

After adding this sleep(1) I ran the test 10 times and I does not fail.
