sc: fix clip cell range for clip with no content

The problem was observed in LOK mode with the following step:
1. Select and copy a sheet area with no content.
2. Paste this into another document.
=> You get an error dialog saying "Protected cells cannot be modified".

The issue here is in ScViewFunc::PasteDataFormat, rSrcDoc.GetDataStart()
gives the correct cell indices of the clip selection, but GetCellArea()
truncates the range to empty range as there is no content. Since these
functions are used in many places which might depend on this behaviour,
it seems right to fix it just for this usecase.
