* Re-add newline before 'react-rails' Gem to fix groupings
Fixes Code Climate issue
Checking reblog vs original status was happening in multiple places
across the app. For views, this logic was encapsulated in a helper
method named `proper_status` but in the other layers of the app, the
logic was duplicated.
Because the logic is used at all layers of the app, we extracted it into
a `Status#proper` method on the model and changed all uses of the logic
to use this method. There is now a single source of truth for this
condition.
We added test coverage to untested methods that got refactored.
* Rewrite Atom generation from stream entries to use Ox instead of Nokogiri::Builder
StreamEntry is now limited to only statuses, which allows some optimization. Removed
extra queries on AccountsController#show. AtomSerializer instead of AtomBuilderHelper
used in AccountsController#show, StreamEntriesController#show, StreamEntryRenderer
and PubSubHubbub::DistributionWorker
PubSubHubbub::DistributionWorker moves n+1 DomainBlock query to PubSubHubbub::DeliveryWorker
instead.
All Salmon slaps that aren't based on StreamEntry still use AtomBuilderHelper and Nokogiri
* All Salmon slaps now use Ox instead of Nokogiri. No touch from status on account
