 * Takes the name of a collection and returns its active index.
 * This function supports collectionName being a dot-separated string
 * of collection names for nested collections:
 *
 * e.g. collectionName being 'flights.people.documents' would return
 * the active index in the nested documents collection, or null if there
 * isn't one or the path is broken.
 *
 * @param {string} collectionName The name of the collection, or dot-separated path.
 * @param {object} data Top-level formData.
 * @returns The active index for the collection, or null if it doesn't exist.
