QLineEdit: Use existing selection when deleting a word

Browse Source 
When using QKeySequence::DeleteEndOfWord or
QKeySequence::DeleteStartOfWord in a QLineEdit with an existing
selection, the selection was ignored which resulted in unexpected
behavior (see bugreport). This is fixed by only setting the selection
if none exists yet.
To prevent an entry in the history when the input is empty, the
selection is checked before calling del().

Fixes: QTBUG-120006
Pick-to: 6.6 6.5
