Incorrect type definition on listIconUrl

[Peter-ChengTszTung]

Expecting listIconUrl?: string; instead of listIconUrl: string;

react-native-airship/src/types.ts

Lines 562 to 567 in 218bfe9

	/**
	* Optional - The icon url for the message.
	*/
	listIconUrl: string;
	/**
	* The unread / read status of the message.

Have the change here - will include in the next release after coming through the rest of the typescript definitions and testing. Thanks again.
