Currently, when the custom flag has the same name as the system flag (which is disabled) then it is not displayed. To fix the problem, `custom_` prefix as `name_key` is used to distinguish between the system and the custom flag.
I considered writing a migration to fix existing custom flags name key. However, at the end of migration I would need to run rails code to reset cache `Flag.reset_flag_settings!`. I decided to skip that step as it is a very edge case. If someone has the same flag name as the system flag, then all they have to do is edit the flag and click save.
In addition, I made 2 small fixes:
- edit flag title was missing translation;
- flag form UI was not showing that description is the required field.
### Why?
Before, all flags were static. Therefore, they were stored in class variables and serialized by SiteSerializer. Recently, we added an option for admins to add their own flags or disable existing flags. Therefore, the class variable had to be dropped because it was unsafe for a multisite environment. However, it started causing performance problems.
### Solution
When a new Flag system is used, instead of using PostActionType, we can serialize Flags and use fragment cache for performance reasons.
At the same time, we are still supporting deprecated `replace_flags` API call. When it is used, we fall back to the old solution and the admin cannot add custom flags. In a couple of months, we will be able to drop that API function and clean that code properly. However, because it may still be used, redis cache was introduced to improve performance.
To test backward compatibility you can add this code to any plugin
```ruby
replace_flags do |flag_settings|
flag_settings.add(
4,
:inappropriate,
topic_type: true,
notify_type: true,
auto_action_type: true,
)
flag_settings.add(1001, :trolling, topic_type: true, notify_type: true, auto_action_type: true)
end
```

The mistake was made when flags were moved to the database. The `notify_moderators` (something else) flag should be the last position on the list.
This commit contains 3 changes:
- update fixtures order;
- remove position and enable from fixtures (they can be overridden by admin and we don't want seed to restore them);
- migration to fix data if the order was not changed by admin.
After flags were moved to the database, with each save they are changing available PostActionTypes. Therefore, flag specs should clear the state before and after each example not just before.
In addition, we need to clear `nil` counts for dynamically created flags from serializer.
