fix triggering mailto: and tel: actions twice

Both the onClicked and onPressed events are defined in emailRepeater and phoneRepeater components; this causes launching the relevant application twice at the same time. Qt's MouseArea documentation states that "A click is defined as a press followed by a release [...]" [1], therefore this fix removes the extra onPressed handlers.
