Investigate problem regarding creating PV Aliases

After choosing to archive a PV: `TE:NDW2452:MOT:MTR0101` the following error occurs. It seems to have no effect on the functionality of the AA. It began appearing after changes were made to the `policies.py`. Looks to be trying to create an alias for this PV, then finds out the alias already has a PVTypeInfo.
