Axel Spoerl 56598b65fa Fix no-op emission of QComboBox::currentTextChanged
currentTextChanged is emitted when the current index changes
and the current text doesn't.
This can be the case, if
- old and new index have identical text values
- an item is removed below the current index

[ChangeLog][Widgets][QComboBox] emit currentTextChanged only,
if currentText changes.

Add a corresponding test in tst_QComboBox::currentText().

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.

Linux X11:

   * The user must be logged in to an active desktop; you can't run the
     autotests without a valid DISPLAY that allows X11 connections.

   * The tests are run against a KDE3 or KDE4 desktop.

   * Window manager uses "click to focus", and not "focus follows mouse". Many
     tests move the mouse cursor around and expect this to not affect focus
     and activation.

   * Disable "click to activate", i.e., when a window is opened, the window
     manager should automatically activate it (give it input focus) and not
     wait for the user to click the window.
