Patch Changes

• Fix some potentially incorrect query plans with @requires when some dependencies are involved. (#2726)

  In some rare case of @requires, an over-eager optimisation was incorrectly considering that
  a dependency between 2 subgraph fetches was unnecessary, leading to doing 2 subgraphs queries
  in parallel when those should be done sequentially (because the 2nd query rely on results
  from the 1st one). This effectively resulted in the required fields not being provided (the
  consequence of which depends a bit on the resolver detail, but if the resolver expected
  the required fields to be populated (as they should), then this could typically result
  in a message of the form GraphQLError: Cannot read properties of null).
