QTabBar: update index of last visible tab in insertTab
Index of the last visible tab was not updated, if a new tab was inserted
after the current tab and before the last tab.
When the new tab is inserted before the last visible tab, the index of
the last tab increments by one.
When the new tab is inserted after the last visible tab, then the newly
inserted tab becomes the last visible.
Fixes: QTBUG-86898
