Pcbnew: avoid crash when saving a board having "orphan" nets. 

Sometimes tracks or zones can have "orphan" nets no longer existing
in schematic after updating the board from the schematic (no pad belonging this net).

The fix does not save these broken nets having no info (no netname, no valid netcode)

Fixes #5087
