On recent gcc-12 snapshot build fails as:

[ 52%] Building CXX object CMakeFiles/TestUnitTest++.dir/tests/TestTestRunner.cpp.o
unittest-cpp/tests/TestTestRunner.cpp:
  In constructor '{anonymous}::FixtureBase::FixtureBase()':
unittest-cpp/tests/TestTestRunner.cpp:48:19:
  error: member '{anonymous}::FixtureBase::reporter' is used uninitialized [-Werror=uninitialized]
   48 |          : runner(reporter)
      |                   ^~~~~~~~
cc1plus: all warnings being treated as errors

On https://gcc.gnu.org/PR103375 Andrew suggested to match order of class
members to avoid picking a member reference to yet unconstructed object.
