It is not allowed to use the Sec-WebSocket-Protocol header for arbitrary values. This was possible due to the raw websocket handling we were doing with Cowboy, but Phoenix.Socket.Transport does not allow this as the value of this header is compared against a static list of subprotocols.
https://hexdocs.pm/phoenix/Phoenix.Endpoint.html#socket/3-websocket-configuration
Additionally I cannot find anywhere that we depended on this behavior. Setting the Sec-WebSocket-Protocol header does not appear to be a part of PleromaFE.
Also consolidate Tesla mocks into the HttpRequestMock module.
Tests were not exercising the real codepaths. The Rich Media Preview only works with https, but most of these tests were only mocking http.
The Rich Media Previews were not regenerated when a post was updated due to a cache invalidation issue. They are now cached by the activity id so they can be evicted with the other activity cache objects in the :scrubber_cache.
lib/pleroma/web/media_proxy/media_proxy_controller.ex:55:no_return
Function handle_preview/2 has no local return.
________________________________________________________________________________
lib/pleroma/web/media_proxy/media_proxy_controller.ex:59:call
The function call will not succeed.
Pleroma.HTTP.request(<<72, 69, 65, 68>>, _media_proxy_url :: any(), [], [], [{:pool, :media}])
will never return since the success typing is:
(
:delete | :get | :head | :options | :patch | :post | :put | :trace,
binary(),
any(),
[{binary(), binary()}],
Keyword.t()
) :: any()
and the contract is
(
method(),
Pleroma.HTTP.Request.url(),
String.t(),
Pleroma.HTTP.Request.headers(),
:elixir.keyword()
) :: {:ok, Tesla.Env.t()} | {:error, any()}

This check was recently improved in Credo and it does make sense for readability.
The offending functions in Pleroma have been renamed and a couple missing the ? suffix have been fixed as well.
