subcontrol-position key error

[Mougrouff]

In NodeGraphQt//widgets/node_widgets.py the following code is causing an issue because key 'subcontrol-position' is not initialized in every situations. Especially if align == 'left'.

if align == 'center':
    style_dict['QGroupBox::title']['subcontrol-position'] = 'top center'
elif align == 'left':
    style_dict['QGroupBox::title']['subcontrol-position'] += 'top left'
    style_dict['QGroupBox::title']['margin-left'] = '4px'
elif align == 'right':
    style_dict['QGroupBox::title']['subcontrol-position'] += 'top right'
    style_dict['QGroupBox::title']['margin-right'] = '4px'

I tried to add'subcontrol-position':'' in style_dict['QGroupBox::title'] , then there was no no more error message.
