This stops adding the current user to the data sent to the API when
removing a user from an organisation. API only needs to know the
organisation_id and the id of the user we want to remove from
the organisation, so we don't need to pass through the id of the
current user too.
The other change made is to clear the user cache of the user who has
been removed from the org. We don't need to clear any of the organisation
caches, since these values don't contain lists of users for the orgs.
It’s weird to have a method just for updating one attribute. I think
the reason for doing this was to only invalidate the
`organisation-{}-name` cache when absolutely necessary, but:
- we don’t need a separate method to check whether it’s the name being
updated
- it was easy to get around this by calling
`OrganisationsClient.update_organisation` directly, leaving a stale
value in the cache
This naming was introduced in 2016 without explanation [1]. I find it
confusing because:
- It's reminiscent of "_app", which is a Python convention indicating
the variable is internal, so maybe avoid using it.
- It suggests there's some other "app" fixture I should be using (there
isn't, though).
The Python style guide describes using an underscore suffix to avoid
clashes with inbuilt names [1], which is sort of applicable if we need
to import the "app" module [2]. However, we can also avoid clashes by
choosing a different name, without the strange underscore.

Before, the delete decorator would delete the keys from Redis and then
we made the request to api to change the data. However, it is possible
that the cache could get re-populated in between these two things
happening, and so would cache outdated data.
This changes the order to send the api request first. We then always
delete the specified keys from Redis. Changing the order of the code in
the decorator changes the order in which the cache keys get deleted, so
the tests have been updated.
This should make the ‘All organisations’ page load a lil’ bit quicker.
Still worth caching the domains separately so the response is smaller
when we only care about domains. This is because the code that uses the
domains is part of the sign up flow, so it’s really important that it’s
snappy.
The domains lookup is a bit slow because it’s serialising all the
organisations in the database. Since we’re putting this in the sign up
flow it should feel snappy, so lets cache just the domain bit of it in
Redis.
