Issue 5784: Better handling for missing parts when replacing parts via "Pod Space"

[psikomonkie]

Fixes #5784

Another "Ghost" bug? It's pretty ghostly I think.

When using the "Pod Space" salvage for a busted location it would also remove "Missing Parts", so when the location is replaced there will be no option to repair the equipment that was a "Missing Part" at the time of the salvage task. This could be worked around be reloading after salvaging.

This fixes that by:

1. Not removing "Missing Parts" when salvaging via Pod Space.
2. Don't count "Missing Parts" as something that needs fixed (otherwise the repair pod space task would always show for missing limbs - this is why when salvaging parts it would show twice, first time would remove initial missing parts and present parts, 2nd salvage would remove the originally-present-now-missing-parts.)
