The non-themed import basically is just a proxy using some
auto-detection to find out which theme to use.
As the app only uses the basic theme, this is what we'll import.
With some delays we allow the user interface to show up so the checkbox
actually is pained to be 'on' when the user gets a question from the OS
about allowing it.
On Android this enables the application to run just a simple
quick sync and then exit the app on regular intervals.
The main benefit is that when the user doesn't run the app very
often they will avoid having a long sync time.
