Patch Changes

• Fix issue where subgraph fetches may have unused fragments (and are thus invalid). (#2628)

• Fix issues in code to reuse named fragments. One of the fixed issue would manifest as an assertion error with a message (#2619)
  looking like Cannot add fragment of condition X (...) to parent type Y (...). Another would manifest itself by
  generating an invalid subgraph fetch where a field conflicts with another version of that field that is in a reused
  named fragment.
