The timer in the ShiftHandler is used for detecting double
click events for shift key. A double click event will trigger
caps lock if the initial shift state is lower case.

However, the implementation did not handle a case where
the keyboard layout changes between the first and second
press. This can be done with multitouch.

The second problem was with the automatic test cases, where
the test code toggles the shift to see if there is a secondary
layout triggered by the shift key, e.g. in Arabic and Farsi.
However, if the keyboard layout does not contain secondary
layout, rapid shift state change will trigger caps lock
instead. This issue was identified with certain test case for
Hebrew layout.

This change fixes the issue by clearing the shift toggle timer
when the layout changes and in the automatic tests while
checking for the secondary layout with the shift key.

Also, update test code so that the shift press is simulated
with mouse. This will ensure the key exists in the layout
and that the key is enabled.

If the Key.alternativeKeys are assigned like:

Key {
    alternativeKeys: condition ? "abc" : "def"
}

it will cause the following QML warning from BaseKey:

[...]/BaseKey.qml:82:32: Unable to assign [undefined] to QString

It seems to be caused by the order in which the dependent
properties effectiveAlternativeKeysHighlightIndex and
effectiveAlternativeKeys are updated.

This change fixes the issue by adding the effectiveAlternativeKeys
as condition for the property assignment.
