History result refactor (#261)

* refactor PNHistoryItemResult Meta and Action fields to be formatted dictionaries instead of plain objects

* fix: issue with publish POST with PAM enabled keyset (#262)

* handle publish POST with secret key, calculate signature as old way

* tests for signature calculation across all http method types

* test-fix: removed unnecessary authtoken for secretKey test case for publish

* test fix, removing invalid characters space from channel name
