reddit.getWidgets(subredditName) errors when sub has an Image Widget without a link

[MrTommyPickles]

If a subreddit has a sidebar with an Image Widget but doesn't include a link in that widget then apps will get an error if they try to call reddit.getWidgets(subredditName). This will affect any app trying to access sidebar information. Example error:

Error: Image widget data is missing linkUrl
