Place a dummy sign to keep sign column.

Browse Source 
The sign column automatically appears when there is at least one sign
and disappears when there are none.  There's a small gap between
when vim-gitgutter removes its signs and adds new ones; during that gap
the sign column can flicker.

By adding a dummy sign before removing the real signs, we force the sign
column to remain.
