[BUG] Wrong result in place explorer page.

[Spaceenter]

Also:
https://autopush.api.datacommons.org/v1/property/values/out/geoId/06/typeOf?key=AIzaSyBCybF1COkc05kj5n5FHpXOnH3EdGBnUz0 (should be State / AA1)

Re the query above, the provenance is https://autopush.datacommons.org/browser/dc/cevjpc -- which is unexpected.

This is because import CensusSuperTMCFTable_ECNBASIC2012_EC1200A1 contains some place nodes, but not all place node, and that import belongs to 'infrequent' import group, which has a higher rank than 'place' import group. Therefore, mixer picks place-related cache from 'infrequent' due to its higher rank than 'place'.

So I think 'place' should probably rank higher than 'infrequent', thus: #1027
But the diffs show some other issues.

Need a bit more thinking re how to merge.
