Bug Description

Execute the code below using qmltestrunner, and the test will fail because 'count' is 2, not 1.

import QtTest 1.0
import QtQuick 2.4
import Ubuntu.Components 1.3

Item {
    id: root
    width: units.gu(50)
    height: units.gu(80)

    Button {
        id: button
        anchors.centerIn: parent
        text: "Click me"
        onClicked: {
            print("click")
        }
    }

    TestCase {
        name: "ButtonClickedSpy"
        when: windowShown
        id: testCase

        SignalSpy {
            id: buttonSpy
            signalName: 'clicked'
            target: button
            onCountChanged: print("new count = "+count)
        }

        function test_click_button() {
            buttonSpy.clear();
            print("spy count after clearing = "+buttonSpy.count);
            mouseClick(button, button.width/2, button.height/2);
            compare(buttonSpy.count, 1, "Could not click button.");
        }
    }
}

and it seems it's not Qt's fault, since it only delivers 1 press and 1 release, as can be seen from

fwiw, the log above was obtained using
QT_LOGGING_RULES="qt.quick.mouse.debug=true"

which is quite handy :)
