Ensure all cells are loaded into memory in netlist_to_spice to avoid file corruption during save 

Added logic to ensure all cells are loaded into memory to prevent corruption when saving files. This is a fix for a minor edge case when generating "netlist_to_spice" for a file that already has a netlist, and which contains cells containing other cells. Followed by "writeall force". This causes unloaded files (that are still referenced) to be loaded during save with "ignoreTech" being true, and thus disregarding the scale, corrupting all coordinates if a scale is used.

This was caused by skipping regenerating cells that already had a .mag file
