PatchFragment with nested fragments

[david-on-github]

When a fragment contains another fragment, patchFragment can't determine which fragment to read from.

fragment someFragment {
    id
    other {
      ...otherFragment
    }
}

ERROR Error: Uncaught (in promise): Error: Found 2 fragments. `fragmentName` must be provided when there is not exactly 1 fragment.

Apollo cache readFragment takes fragmentName as an option to determine this.

Also having this problem with nested fragments, did you come up with a solution?
