Have consistent behaviour for submit button fields

Currently submit button fields are used both in single and in list/grid forms. Commonly these are defined with following code:

        <field name="submitButton" title="${uiLabelMap.CommonUpdate}" widget-style="smallSubmit">
            <submit button-type="button"/>
        </field>

The behaviour in a form of type="single" is different than that in a form of type="list" or in a form of type="grid".

In a form of type="single" the title is not displayed as a label, yet in the list/grid form it is.
