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.

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
It's very easy to forget to add `require 'rails_helper'` at the top of every core/plugin spec file, and omissions can cause some very confusing/sporadic errors.
By setting this flag in `.rspec`, we can remove the need for `require 'rails_helper'` entirely.
Over the years we accrued many spelling mistakes in the code base.
This PR attempts to fix spelling mistakes and typos in all areas of the code that are extremely safe to change
- comments
- test descriptions
- other low risk areas
* Introduced fab!, a helper that creates database state for a group
It's almost identical to let_it_be, except:
1. It creates a new object for each test by default,
2. You can disable it using PREFABRICATION=0
This change both speeds up specs (less strings to allocate) and helps catch
cases where methods in Discourse are mutating inputs.
Overall we will be migrating everything to use #frozen_string_literal: true
it will take a while, but this is the first and safest move in this direction
