Use a better check for existence of the NERDTree buffer.

Browse Source 
If the user wipes out or deletes (:bw or :bd) the NERDTree buffer, there
is still a tab variable that hangs onto the name of that now-missing
buffer. Checking only that variable is not enough to decide whether to
create a new NERDTree or use the existing one. Fortunately, there
already is a function with a more complete check: ExistsForTab()
