Title: #32: Fix subtree() cannot cooperate with rsearch()

1. subtree() hasn't taken care the original bpointer of it's root node
which broke rsearch().
2. Add a if-condition on rsearch() to make sure it will break if
tree.root (string) equals current (string)

Note: There are 2 solutions I can come up with which are modifying codes in subtree() or rsearch(), this one is modifying rsearch()
