Code Issues Proposed changes

Fix TypeError in nova-manage cell_v2 list_cells 

Cell mappings don't require a name, so when listing
cells, if any mappings don't have a name, the sorted
function will fail with a TypeError since you can't compare
None to a string.

This fixes the issue by using the empty string if the cell
mapping name is None.
