One of these tests has failed in our CI with the following message:
```
1) Users Public activity user can hide public page
Failure/Error: expect(page).to have_content("activity list private")
expected to find text "activity list private" in "Language: \n

```
Note how the text "User has no public activity" is present, which is a
message that appears when the user's activity is public.
A possible explanation is that we didn't check that the request done by
the "Save changes" button had finished before continuing with the tests.
Back when we wrote this test, submitting a form in a test would always
wait for the request to be finished before continuing, but a lot has
changed since then.
So we're adding an expectation to make sure the the changes have been
saved before making a new request.
We're also rearraging the blank lines in these tests and removing the
parenthesis in `have_content` expectations to be consistent with the
expectations we're adding.
