## About the changes
This makes sure that projects have at least one owner, either a group or
a user. This is to prevent accidentally losing access to a project.
We check this when removing a user/group or when changing the role of a
user/group
**Note**: We can still leave a group empty as the only owner of the
project, but that's okay because we can still add more users to the
group
Sort array items before running compare. Feature flag certain properties
of strategy that were previously not present in the /api/admin/features
endpoint.

This adds 2 methods to `EventService`:
- `storeEvent`;
- `storeEvents`;
This allows us to run event-specific logic inside these methods. In the
case of this PR, this means fetching the feature tags in case the event
contains a `featureName` and there are no tags specified in the event.
This prevents us from having to remember to fetch the tags in order to
store feature-related events except for very specific cases, like the
deletion of a feature - You can't fetch tags for a feature that no
longer exists, so in that case we need to pre-fetch the tags before
deleting the feature.
This also allows us to do any event-specific post-processing to the
event before reaching the DB layer.
In general I think it's also nicer that we reference the event service
instead of the event store directly.
There's a lot of changes and a lot of files touched, but most of it is
boilerplate to inject the `eventService` where needed instead of using
the `eventStore` directly.
Hopefully this will be a better approach than
