.ignore() does not apply to included resources

[ryabrody]

In our app we are working with following user (localch-accounts) resource:

{
  "href": "http://api.test/localch-accounts/p62qM5p0NK_qryO52Ze",
  "id": "p62qM5p0NK_qryO52Ze",
  ...
  "language": "de",
  "created_date": "2015-06-30T09:54:59.858+02:00",
  "claims": {
    "href": "http://api.test/localch-accounts/p62qM5p0NK_qryO52Ze/claims",
    "items": [
      {
        "href": "http://api.test/localch-accounts/p62qM5p0NK_qryO52Ze/claims/A00OhenWd_Z5RWnxDE7mqA",
        "localch_account": {
          "href": "http://api.test/localch-accounts/p62qM5p0NK_qryO52Ze"
        },
        "place": {
          "href": "http://api.test/places/A00OhenWd_Z5RWnxDE7mqA"
        },
   ...
}

When fetching the user (localch-accounts) we include the claims and also the place:

User.includes([claims: :place]).find('p62qM5p0NK_qryO52Ze')

Now it could be that a place does not exist anymore and we want to avoid running into a 404 by using .ignore(LHC::NotFound).

User.ignore(LHC::NotFound).includes([claims: :place]).find('p62qM5p0NK_qryO52Ze')

I now would expect that no 404 are raised.
But a 404 is raised because of a missing place.

With following references i can achieve the desired behavior but i would also expect this by just using ignore() as described above.

User.includes([claims: :place]).references(current_user_references).find('p62qM5p0NK_qryO52Ze')
...
def current_user_references
  [
    {
      claims: {
        place: {
          ignored_errors: [LHC::NotFound]
        }
      }
    }
  ]
end
