check pastro of mdc12 noninj uploads

We have checked pastro of triggers uploaded from the inj channel, but haven't looked into pastros of triggers uploaded from the non-inj channel. The following should be checked for mdc12 since we are using a different pastro model.

• check that non-GW events are not given low pTerr. (Maybe make a pp-plot for the non-inj channel uploads. If that is not conclusive/sufficient, maybe loop over the non-inj channel uploads and print out gracedb ids of triggers with pTerr below some threshold value or low in relative to pBNS/pNSBH/pBBH?)
• check that pastro adds up to 1. (Maybe have a short script to loop over the non-inj channel uploads and check that their pastro probabilities add up to 1.)
• check that terrestrial events are given large pTerrestrial
• check that GW pastro probability is consistent with the true source. (There are about 10 GW events. I would check them manually.)
