Explicit destruction order in gcm_unit_tests

Explicit destruction order in gcm_unit_tests

I looked through the cs.chromium.org results for

codedoutputstream -file:.pb.cc -file:.java -file:.pb.h

but don't see any other instances of this exact problem in
non-test code (and in fact, some with similar looking
constructs: https://code.google.com/p/chromium/codesearch#chromium/src/third_party/protobuf/src/google/protobuf/io/coded_stream_unittest.cc&l=320 )
