fix(label): left/right pointing interferes with icon

left/right pointing labels interfered with pure icon labels.
I changed this so people have have to explicisely set left icon in addition to right pointing. Therefore i tag this as a breaking change.
This change now also allows to have a left icon while also having a right close/delete icon
