Tomasz Grabiec 7c3e6c306b row_cache: Wait for in-flight populations on update ...

Before this change, populations could race with update from flushed
memtable, which might result in cache being populated with older
data. Populations started before the flush are not considering the
memtable nor its sstable.

The fix employed here is to make update wait for populations which
were started before the flushed memtable's sstable was added to the
undrelying data source. All populatinos started after that are
guaranteed to see the new data.
