Prevent UM restart files being archived to output

[MartinDix]

Fix is to remove the restart files from the work directory after the last one is copied.

Previously in archive/pre-industrial/output000/atmosphere there were 12 monthly restart files aiihca.daa*

What was the intention of creating monthly restart files? Would this affect someone who only wants to run the model for 6 months?

[MartinDix]

The UM has a climate mean facility which we use to generate monthly means. This is tied in with the restart dumps in a complicated way which means creating less than monthly restarts is not practical.

payu copies the last restart file of the run to the restart archive. However since the restarts are in the same work directory as the diagnostics we actually want, they will unncessarily get archived to output unless removed.
