[regression] Tab switcher doesn't work if a text field is focused

[Michael Sheldon]

Steps to reproduce:

1) Run the following QML:

import QtQuick 2.0
import Ubuntu.Components 1.0

MainView {

    useDeprecatedToolbar: false
    anchorToKeyboard: true

    Tabs {

        Tab {
            title: "Test"

            Page {
                title: "Test"
                TextField {
                    anchors.centerIn: parent
                }
            }
        }

        Tab {
            title: "Test 2"

            Page {
                title: "Test 2"
            }
        }

    }

}

2) Tap the input field

3) Tap the tab switcher

Expected outcome:

Tab menu should appear

Actual outcome:

Tab menu doesn't appear unless the keyboard is dismissed first (which removes input focus from the field).

This is present on vivid-proposed image #84 and doesn't exist on RTM.

I tested this on mako and the bug no longer exists.
