Do not use a dummy sign to prevent sign column flicker.

Browse Source 
In fe2b4ec869 (from 2013) the plugin
started using a dummy sign to prevent the sign column briefly
disappearing then reappearing when updating signs.

Since then Vim has vastly improved its handling of signs and the sign
column no longer flickers like this.
