Update apollo-client in / from 2.0.3 to 2.4.1

[dependencies]

Dependencies.io has updated apollo-client (a npm dependency in /) from "2.0.3" to "2.4.1".

2.4.1

• mutate's refetchQueries option now allows queries to include a custom
  context option. This context will be used when refetching the query.
  For example:

  context = {
    headers: {
      token: 'some auth token',
    },
  };
  client.mutate({
    mutation: UPDATE_CUSTOMER_MUTATION,
    variables: {
      userId: user.id,
      firstName,
      ...
    },
    refetchQueries: [{
      query: CUSTOMER_MESSAGES_QUERY,
      variables: { userId: user.id },
      context,
    }],
    context,
  });

  The CUSTOMER_MESSAGES_QUERY above will be refetched using context.
  Normally queries are refetched using the original context they were first
  started with, but this provides a way to override the context, if needed.
