Bug 27251: Don't hide the table on delete if empty

If we filtered the result, delete the only row displayed then the table
was hidden. This is a nice behaviour, especially if there was no filter.
However we must show it again if the filters are removed.
I am suggesting to simply to not hide the table and avoid adding more JS
code to deal with this very specific use case.
