[REVIEW-3-5] fix for fdo#48449, check for column/rows for autofill and not filtered areas

[Markus Mohrhard]

Hey,

[1] fixes that autofill is not working correctly as soon as there is a
filtered area on the sheet. Additionally it switches from filtered
areas to hidden rows/columns because this makes more sense. The
problem has been that before the patch we checked if there is a
ScDBData filtering any part of the table. Instead the important fact
is if there is a hidden column/row in the autofill area.

The patch should be quite safe and fixes two bugs at once therefore I
think we can include it into 3-5

Regards,
Markus
