#335 Persistence: About screen

[Christa Runge]

Scenario (svn 2901 / version 1.7.5 beta):
- in the list of databases press the 'i' icon and see the About screen as expected.
- exit application and restart. See the about screen as expected.
- press the 'Done' button and see the list of databases.
- select a database and press the 'i' button. See the database info screen as expected.
- press the 'Done' button and search for uncommitted cards. See the list as expected.
- enter a search string and see the list of matches.
- search for uncommitted cards and see the list as expected.
- press the 'back' button and see the list of categories.
- press the 'back' button.
Expected behavior: See the list of databases.
Observed behavior: see the About screen.

Note: this scenario is not always reproducible. I have seen it as described several times on my iPodTouch (iOS 4.0). However, more often a saw normal behavior as expected. Can a race condition or a low memory warning be involved?

Hopefully this is resolved with refactoring of the view hierarchy at startup (Startup View Controller is now the root view).
TODO: test it.

Not seen again. We regard this as resolved.
Tested on iPad Air 2 (iOS 11 beta) at svn 3563.
