As setValueFromStorage() notes, we can accept either JSON strings or arrays for PHID-type custom fields. Handle this in decodeValue by passing through an array if we've received one.

Test Plan:
  - Add Maniphest custom field with PhabricatorPeopleDatasource
  - Create task with field filled
  - Go to Maniphest task detail view
  - Observe no errors in DarkConsole / PHP error log
