Work around mysterious button text not matching string

The test works just fine on API 33, but on API 34 the string "4:05 AM"
will never match, even though the actual textView looks exactly right.
Strangely, matching any whitespace character instead of the space
between "4:05" and "AM" works. I have no idea what is going on. And no
other tests behave like this.
