Don't prefix test output with ">>>". Ticket #848. Removing the prefix brings "cabal test" in line with other cabal commands, which do not prefix their output, either. Prior to this patch, the summary notices which appear before and after each test suite were written to the temporary log file along with the stdio from the test executable; this would lead to duplicate notices when the contents of the temporary log file are read onto the console. After this patch, the summary notices are never written to the temporary log file, only to the console and the final log file (which is never read by Cabal), removing the confusing duplicate notices.
