[bugfix] 2643 bug search for account url doesnt always work when redirected (#2673)
* update activity library so dereferencer returns full response and checks *final* link to allow for redirects

* temporarily add bodged fixed library

* remove unused code

* update getAccountFeatured() to use dereferenceCollectionPage()

* make sure to release map

* perform a 2nd decode to ensure reader is empty after primary decode

* add comment explaining choice of using Decode() instead of Unmarshal()

* update embedded activity library to latest matching https://github.com/superseriousbusiness/activity/pull/21

* add checks to look for changed URI and re-check database if redirected

* update max iteration count to 512, add checks during dereferenceAncestors() for indirect URLs

* remove doubled-up code

* fix use of status instead of current

* use URIs for checking equality for security

* use the latest known URI for boost_of_uri in case original was an indirect

* add dereferenceCollection() function for dereferenceAccountFeatured()

* pull in latest github.com/superseriousbusiness/activity version (and remove the bodge!!)

* fix typo in code comments

* update decodeType() to accept a readcloser and handle body closing

* switch to checking using BoostOfID and add note why not using BoostOfURI

* ensure InReplyTo gets unset when deleting status parent in case currently stubbed

* add tests for Collection and CollectionPage iterators
