the class IntentRemoveCommand method removeIntent.

/**

 *
 * If an application ID is provided, it will be used to further
 * filter the intents to be removed.

 * @param intents list of intents to remove
 * @param applicationIdString application ID to filter intents
 * @param keyString string to filter intents
 * @param purgeAfterRemove states whether the intents should be also purged
 * @param sync states whether the cli should wait for the operation to finish
 *             before returning
