tdf#114228: fix crash when deleting sheet in specific case

1. Create a brand new ods file
2. Select L12 (so cursor is obviously on sheet1 L12)
3. Create a brand new sheet (and cursor is on sheet2 A1)
4. Delete sheet2

It crashes with gtk3, see https://bugs.documentfoundation.org/attachment.cgi?id=138199
As indicated in https://bugs.documentfoundation.org/show_bug.cgi?id=114228#c5 the tab number
is wrong
Reporting cursor management later in ScTabView::SetTabNo prevents from the crash
