This is a fix very similar to #7283 but in a slightly different place, which will hopefully address #6700. I can't reproduce the issue, so I'm not sure it fixes it.
The idea is that
inputDrvOutputs
is statefully constructed and is somehow not getting set properly. Rather than track down that bug (which would also be good to do at some point), this piece of duct-tape just checks the actual store as a backup wheninputDrvOutputs
doesn't have it.
