Fixed two independent errors, both of which can cause devices to be 

missing from a netlist generated by ext2spice with the "extresist"
option enabled.  The first had to do with some parts of nets being
given alias names for a net, and the second was caused during
"extresist" and would also result in error messages about devices
missing terminals.
