This should fix
#485

Fix issue with restart filenames when using ensembles.

Moved call for filename_appendix outside of loop.

Fixes issue where restart filename was
./MOM.res.ens_01.nc
./MOM.res.ens_01.ens_01_1.nc
./MOM.res.ens_01.ens_01.ens_01_2.nc
./MOM.res.ens_01.ens_01.ens_01.ens_01_3.nc

instead of
./MOM.res.ens_01.nc
./MOM.res.ens_01_1.nc
./MOM.res.ens_01_2.nc
./MOM.res.ens_01_3.nc
