Fixes all tests to pass on most machines

Everyone who runs the "make test" may have different default Yaf`s INI
settings.

* in case the yaf.use_namespace=1 almost all tests fails
* in case the yaf.environ=dev around 5 tests fails
* in case the yaf.use_spl_autoload=1 one test fails

This fix specifies necessary INI values to pass all the tests.
