The majority of the test reuses testWidget. While this may be faster
than creating a QDateTimeEdit instance on the stack for each test,
it introduces issues when certain properties aren't unset when cleaning
up. This happens easily when new tests are introduced which rely on
certain properties, for example.
Rather than making the newly introduced step-modifier-related tests
use testWidget, this patch goes with the simpler option of hiding
testWidget, just like other tests currently do.
Eventually we should probably switch to using local instances
everywhere.
