gaussConvectionScheme: Removed temporary warnUnboundedGauss debug switch

which provided warning about backward-compatibility issue with setting div
schemes for steady-state.  It caused confusion by generating incorrect warning
messages for compressible cases for which the 'bounded' should NOT be applied to
the 'div(phid,p)'.
