Currently, if an association is added as a tracked field in
`PostRevisor`, the `PostRevisionSerializer` class will try to serialize
it somehow. This will raise an error as ActiveRecord collection proxies
can't be serialized.
This patch addresses this issue by skipping any association tracked by
the `PostRevisor` class.
In some instances, the `modifications` of `tags` hasn't been properly serialized as a Ruby array but rather as a string (I've seen `""`, `"[]"`, and `"[\"\"]"`).
This generates an error when we try to `filter_tags` and remove `hidden_tags` (which is an array) from `tags` which might be a string.
Internal ref - t/131126
I wasn't able to figure out the root cause of this so I reverted the behavior that was introduced ~6 years ago in f2c060bdf2
- FIX: properly scope category changes to what the current user can see
- UX: previous category is now highlighted in "red", new category is highlighted in "green"
- PERF: no need to serialize the categories
- FIX: properly track wiki
- FIX: properly track post_type (aka. Staff Color)
- FIX: properly track making a topic a PM
- FIX: never show the category changes when a topic is made a PM
- PERF: post_revision serializer is now more leaner (never includes title changes when post_number > 1, never includes user changes if there aren't any)
- UX: always sort the tags by name
When lazy load categories is enabled, categories should be loaded with
user activity items and drafts because the categories may not be
preloaded on the client side.
When tagging is enabled, we were correctly serializing tags by their name. However, when tagging was disabled we were attempting to serialize an entire Tag object which raises an error since ee07f6da7d.

This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
FIX: history revision can now properly be hidden
FIX: PostRevision serializer is now entirely dynamic to properly handle
hidden revisions
FIX: default history modal to "side by side" view on mobile
FIX: properly hiden which revision has been hidden
UX: inline category/user/wiki/post_type changes with the revision
details
FEATURE: new '/posts/:post_id/revisions/latest' endpoint to retrieve
latest revision
UX: do not show the hide/show revision button on mobile (no room for
them)
UX: remove CSS transitions on the buttons in the history modal
FIX: PostRevisor now handles all the changes that might create new
revisions
FIX: PostRevision.ensure_consistency! was wrong due to off by 1
mistake...
