fixed location error place/2021 and place/2475

place/2021 (Mar Nuh church in Dairek) included the surrounding village
and the large region, but not the smaller region around the village and
within the larger region.  place/2475 was listed as within Dairek, but
it actually wasn't; it was only *near* Dairek, so I removed Dairek from
its nested <location> and instead added an abstract and a relative
location which is a quote from Wilmshurst's EOCE.
