Upgrade JUnit to 4.13.2

ExpectedException is deprecated, so I fixed the new warnings. However,
we are still using ExpectedException many places and had previously
supressed the warning. See
#7467 . I did not fix those
existing instances that had suppressed the warning, since it is
unrelated to the upgrade and we have been free to fix them at any time
since we dropped Java 7.
