hgtagsfnodescache: handle nullid lookup The null revision is empty, so it `.hgtags` content is `nullid` in regards with the `hgtagsfnodescache`. Dealing with `nullid` will help with the next changeset. Before this change, feeding `nullid` to `hgtagsfnodescache.getfnode` would return a wrong result (fnode for tip).
