fix(Tabs): default shouldSelectOnPressUp to true if item is a link

[reidbarber]

Defaults shouldSelectOnPressUp to true in useTab when the item is a link.

Fixes an issue where when beforeunload was used and the navigation was cancelled by the user, the browser would re-open the dialog when the link was hovered again.
