Subject: [PATCH] Pleroma.Web.MastodonAPI.AccountController: dialyzer errors

lib/pleroma/web/mastodon_api/controllers/account_controller.ex:479:call
The function call will not succeed.

Phoenix.Controller.render(
  _conn :: %{
    :assigns => %{:account => _, :user => _, _ => _},
    :body_params => %{:comment => _, _ => _},
    _ => _
  },
  <<114, 101, 108, 97, 116, 105, 111, 110, 115, 104, 105, 112, 46, 106, 115, 111, 110>>,
  [
    {:target, %Pleroma.User{:id => _, _ => _}} | {:user, %Pleroma.User{:id => _, _ => _}},
    ...
  ]
)

will never return since the success typing is:
(
  %Plug.Conn{
    :adapter => {atom(), _},
    :assigns => %{atom() => _},
    :body_params => %Plug.Conn.Unfetched{:aspect => atom(), binary() => _},

  },
  atom() | binary(),
  atom() | binary() | [{_, _}] | map()
) :: %Plug.Conn{
  :adapter => {atom(), _},
  :assigns => %{atom() => _},
  :body_params => %Plug.Conn.Unfetched{:aspect => atom(), binary() => _},
  :cookies => %Plug.Conn.Unfetched{:aspect => atom(), binary() => _},

  :port => char(),
  :private => %{atom() => _},
  :query_params => %Plug.Conn.Unfetched{
    :aspect => atom(),
    binary() => binary() | [any()] | map()
  },
  :query_string => binary(),
  :remote_ip =>
    {byte(), byte(), byte(), byte()}
    | {char(), char(), char(), char(), char(), char(), char(), char()},
  :req_cookies => %Plug.Conn.Unfetched{:aspect => atom(), binary() => binary()},
  :req_headers => [{_, _}],
  :request_path => binary(),
  :resp_body =>
    nil
    | binary()
    | maybe_improper_list(
        binary() | maybe_improper_list(any(), binary() | []) | byte(),
        binary() | []
      ),
  :resp_cookies => %{binary() => map()},
  :resp_headers => [{_, _}],
  :scheme => :http | :https,
  :script_name => [binary()],
  :secret_key_base => nil | binary(),
  :state => :sent,
  :status => nil | non_neg_integer()
}

and the contract is
(Plug.Conn.t(), binary() | atom(), Keyword.t() | map()) :: Plug.Conn.t()

________________________________________________________________________________
lib/pleroma/web/mastodon_api/controllers/account_controller.ex:519:call
The function call will not succeed.

Plug.Conn.assign(
  _conn :: %{:body_params => %{:uri => _, _ => _}, _ => _},
  :account,
  _user :: %Pleroma.User{_ => _}
)

breaks the contract
(t(), atom(), term()) :: t()
