Supplying null as a callback to WKWebsiteDataStore.getDefaultDataStore.removeData causes crash

[klianc09]

Issue details

Calling WKWebsiteDataStore.getDefaultDataStore().removeData and passing 'null' as the Runnable callback will cause a crash.
Usually when a Runnable is used as a callback handler, one can just pass in null, and it will work fine.
Workaround is simple, just supply an empty lambda.

Reproduction steps/code

WKWebsiteDataStore.getDefaultDataStore().removeData(WKWebsiteDataStore.getAllWebsiteDataTypes(), NSDate.getDistantPast(), null);
