Update IPHBubbleDelegateImpl to use incognito profile when called

incognito.

This CL update the profile passing to TrackerFactory and
DownloadManagerService from IPHBubbleDelegateImpl. Currently, it is
always regular profile, however it is not safe because of possible data
leakage from incognito to regular profile.

Therefore, this CL uses the profile (i.e., regular or off-the-record
profile) belong to active tab in IPHBubbleDelegateImpl,then passes it to
TrackerFactory and DownloadManagerService.
