Title: Support non-ObjectID ids being given to modifiers.

The partially broken by cf82ec6e where it allowed a single ID to be
passed and it would work as expected. This also adds support for
multiple IDs to be provided.

Ran into this issue today updating an app from 0.9.2 to 0.12.0 (originally semi-broken in 0.11.1).
