e.g. when the user changes the email while having a mail selected,
it gets unselected (albeit briefly) and update will be called
with 'undefined'
this throws an error, so prevent this by always supplying an object

As the <b> tag in combination with extjs resulted in a "font-weight:
bolder" setting which was not rendered correctly in Firefox.
Use our own css class to set font-weight to bold.
