Support find_all with an array of IDs

[gburgett]

Algolia rails gem provides the ability to search activemodel records like this:

Person.search('some query')

The way this works is, when the hits come back, it gets an array of all the IDs and then passes them to a call to .where(id: array_of_ids). Our ActiveRecordShim passes this through to find_all, which via the CDNAdapter results in this error:

WCC::Contentful::SimpleClient::ApiError
AlgoliaSyncJob@default
The query you sent included duplicate URI query parameters. Please specify each URI query parameter only once and separate multiple values with a comma, e.g. "order=foo,bar".
Duplicates were: sys.id[]
