Common lib: track down and fix "day one" bug with linear has insert resulting in bucket's list order violation in the case where the inserted element's key is less / precedes the heads element's key, which, in turn, could potentially lead to insertion of duplicates. The problem didn't show up earlier due to lack of duplicate key insertion attempts in the logic that used linear hash table prior to use of linear hash table with chunk read leases.
Common library: fix dynamic array swap method by adding swap of the last buffer index instance variable.
