goog.structs.trie.remove(key) always removes parents #519

Open GoogleCodeExporter opened 9 years ago

What steps will reproduce the problem?
1. If you have a node with key abc and a child node with key abcd, removing 
abcd removes abc too if abcd is the last child node of abc.

What is the expected output? What do you see instead?
If abc has a value, it should not be removed. Only if the parent does not have 
a value it should be removed.

What version of the product are you using? On what operating system?
