Allow title display of static contact element to be invisible or none

[AsylumSeekersCentre]

Overview

This twig template change enables the expected behaviour of setting the element Title Display to 'invisible' or 'none'.

Before

If you create a webform with a CiviCRM Contact element, set the Form Widget to Static, and set the Title Display for that element to 'invisible' or 'none', the Title is still displayed.

After

Setting the Title Display to 'invisible' will result in the label gaining the hidden attribute. Setting the Title Display to 'none' will omit the label from the output.

Technical Details

This changes two lines of the Twig template, adding to one existing conditional so the label will be omitted if the #title_display is 'none', and then adding a new conditional to decide whether the label should get the hidden attribute.
