Fixed

• Fix infinite loop bug in Test Mocks (#842): Thank you to @AlexPan1992 for raising the issue.
• Improve error description formatting for validation failure (#846): GraphQL validation errors encountered while running code generation are now formatted to be easier to read in logs. Thank you to @dfed for the contribution.
• Fix deadlock in AsyncReadWriteLock (#851): When under heavy loads, the AsyncReadWriteLock used by the ApolloStore could cause a deadlock. This is now resolved. Thank you to @marksvend for raising the issue.
• Fix cancellation error for single response operations (#855): When a single response operation was cancelled, a .noResults error was thrown instead of the expected CancellationError. This is now resolved. Thank you to @3redrubies for raising the issue.
• Fix multipart parsing error (#852): When a multipart message was received with characters after the closing boundary the multipart parser would emit a cannotParseChunkData parsing error. This is now resolved. Thank you to @ecant for raising the issue.
