Add test to check independece of getLocale and hideDefaultLocale (#657)

* Add test to check independece of getLocale and hideDefaultLocale

A recent change in `setLocale` caused that `hideDefaultLocaleInURL`
is causing a `404` error when an uri with default locale is accessed.
A test for this scenario has been created, but it currently fails
in release 1.4.2.

See #656 for more
