Update apollo-client in / from 2.0.3 to 2.3.8

[dependencies]

Dependencies.io has updated apollo-client (a npm dependency in /) from "2.0.3" to "2.3.8".

2.3.8

• Adjusted the graphql peer dependency to cover explicit minor ranges.
  Since the ^ operator only covers any minor version if the major version
  is not 0 (since a major version of 0 is technically considered development by
  semver 2), the current ^0.11.0 || ^14.0.0 graphql range doesn't cover
  0.12.* or 0.13.*. This fixes the apollo-client@X has incorrect peer dependency "graphql@^0.11.0 || ^14.0.0" errors that people might have
  seen using graphql 0.12.x or 0.13.x.
