Get rid of the CppUnit-compatible macros in these tests and use Catch TEST_CASE() and CHECK()/REQUIRE() directly instead. No real changes, except for enabling the previously mistakenly (they were clearly meant to be) not run RefUnsignedCharAssignmentOperator and RefUnsignedCharParenOperator tests in unichar.cpp. Moreover, one of them turned out to be broken and had to be fixed here as it does run now.
