For explicit unscoped authentication, the keystome server
specifies the scope parameter value as 'unscoped'. However
keystoneauth1 initialises it to {'unscoped': {}}. This
patch removes this inconsistency.
Updated the corresponding test for unscoped request which
checks the scope parameter in auth to match the 'unscoped'
string.
