Substituting keyPressEvent with keyReleaseEvent to fix bug # 321967
Review Request #115223 - Created Jan. 22, 2014 and submitted
text() gets updated only after keyPressEvent thus URL might be trimmed of last character or charaters in case of user is fast-typer. Replacing event with keyReleaseEvent, however, fixes the problem: text() is updated before it happens. https://bugs.kde.org/show_bug.cgi?id=321967
