Reactivate all text editor tests

Due to the Monaco uplift, we had to temporarily skip a test, because
it affected the default preference regarding auto-save.

To re-enable the test, we now explicitly set the auto save preference to
`off` before the test. This way the preference value is ensured to be
consistent.

Fixes #10891
