Dialog reappear when activity is recreated (e.g. upon rotation)

What steps will reproduce the problem?
1. Open the about dialog
2. Press back to dismiss the dialog
3. Rotate device

What is the expected output? What do you see instead?
Expect that the dialog will not reappear, but it does.  This occurs for all 
dialogs (about and changelog), in both activities (e.g. Tefilla and initial), 
and for all recreations (e.g. rotation, switching into and out of tefilla.)

Please use labels and text to provide additional information.
This has to do with the Activity maintaining the state of displayed dialog but 
not updating it upon dialog dismissal.

This is annoying now, but will be worse once everyone has a dialog open for 
them - e.g. the changelog
