Removed the duplicate tests. Thanks for the review!

Seems, removed tests decrease MSI. Kill muatant.

Updated the data providers instead: DEFAULT yields now don't call uncheckValue(null), keeping the hidden input in the expected output. This covers the code path the removed tests used to cover and should fix the MSI drop.

Now data providers contains too much parameters. Tests looks difficult. Can it be simplified somehow? Maybe instead of edits, add new tests?
