Refresh children of directory nodes on "reveal()"
The ":NERDTreeFind" command calls the "reveal()" method on the
NERDTree root node. The "reveal()" method would, in turn, call the
node's "open()" method. Since the "open()" method would only
initialize the child nodes of the root (i.e., read them from disk)
when the list of child nodes was empty, new paths would not be
included in the list.
This commit will result in the refreshing of the child node list
whenever "reveal()" is called on a directory node (unless it is the
first time the node is being opened... the most efficient option).
The result is that ":NERDTreeFind" will discover newly created paths
that exist on disk but are not cached in the NERDTree.
A stray debugging message is also removed.
Fixes issue #779.
