fix(tables): clear row selection after context-menu delete

handleContextMenuDelete dispatched the delete but left rowSelection at
its prior 'all' or 'some' state. After rows clear and a new row arrives
(realtime, undo, append), rowSelectionIncludes returned true for it,
rendering it checked and flipping the master checkbox back on.
