At least on Windows (didn't have the time to test on Linux yet),
running tests, even if they passed, there would be an Eina error on logs
pointing that a temporary file wasn't closed:
ERR:eina_file ../src/lib/eina/eina_file_common.c:1137 eina_file_shutdown() File [C:/Users/joao_/AppData/Local/Temp/aaaa_file_test_EBpVea] still open 1 times !
In the end, it was the eina_file_test_unlink that would create a temporary
file but never close it, being caught only by eina_shutdown().
