Title: fixing bug with launching dialog from UIAlertView

This commit fixes the following bug:
---
Steps:
Have an application launch a Facebook dialog immediately after the user clicks on a UIAlertView button. (e.g. from the `- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex` method. Launch the alert view and then click said button.

Expected Result:
A Facebook dialog pops up.

Actual Result:
The dialog pops up for a fraction of a second, and then is immediately dismissed.
