Fixed: Was getting an error about the original source for 'auth_shared_login_bar' having changed,
but our 'auth_shared_login_bar' override didn't even *have* an :original option set. So it must have
been the 'auth_shared_login_bar' from spree_auth_devise. Yet adding an :original option to this
override gets rid of the error, so that's odd.

Deface: [ERROR] The original source for 'auth_shared_login_bar' has changed, this override should be reviewed to ensure it's still valid.
