GetMemberPropertiesTest: work round removal of exception related annotations

Expecting exceptions via annotations was deprecated in PHPUnit 8.x and removed in PHPUnit 9.0.0 in favour of using the `expectException*()` methods.

This does need a work around for PHPUnit 4.x in which the `expectException*()` methods didn't exist yet, but as this only applies to two tests, that's not a big deal.
