Add specs to check for designs fields
---------------------------------------

This also includes changes derived from review feedback:

* Move parameter validation to separate method
* hide private implementation
* use named parameters

Add requests to test full GraphQL lifecycle
---------------------------------------------

This adds new GraphQL feature tests to verify the ability to query for
designs and designs-at-versions throughout the graph

Add tests for pagination
----------------------------

This adds tests for pagination over designs, versions and
designs-at-versions

It also changes graphql_helpers so that attribute serialization is now
sensitive to the type of the argument (so that pagination arguments can
be passed easily), which required changes elsewhere
in the codebase.

This is mediated through a `designCollection` object to avoid
polluting the Query object

This mounts the new resolvers on the design collection type

* Add design-at-version resolution

This adds separate singular and plural resolvers for design-at-version,
with tests and references in the design-type.

DesignsAtVersionResolver is nested under Version - This reflects the
fact that this particular resolver requires that it is mounted on a
version

This also importantly ensures that only singular arguments are passed in
singular context, and only plural ones in plural context. Mutually
incompatible arguments are detected and raised as errors.

Equally importantly, this ensures that any objects we fetch by ID have
to pass the same reference checks as the other ways of resolving them,
and they must be coherent with  the implicit version context, and
visible at that version.

Three variants of version resolvers are distinguished:

* when there is no relevant context (e.g. top level):
  - singular resolver able to retrieve versions by ID
* when there is a relevant context (a source of versions)
  - plural resolver to find all versions up-to a given version
  - singular resolver to find a version by ID or SHA

Resolvers are split up into custom singular versions where this makes
code simpler.

Single resolvers return self as single form

This introduces a shared context for efficiency

* Add current_user method to base resolver

  This is used often enough to be of general utility

* Allow resolving lazy values when calling resolvers

  Have distinct resolve and eager_resolve methods, so that tests can
  decide if they want laziness handled transparently or not.

* Add Design.visible_in? method and specs

  This tests that a design is visible at a particular version.

* Improve Designs finder

  Finders should return none when given empty arrays

  Adds missing parameter to documentation comment on DesignsFinder
