[32852] Use the baseRoute in redirecting back from destroyy modal

All split and full views have the baseRoute set to go back to the
list/grid/ifc page, so we can use this to decide whether we want to use
the `backRoute`.

In the bug, the backRoute is empty, so we go back to the default
work-packages.list
