Fix memory leak in unit test node_algorithm_black (#4670)

Commit ccd4500 modified the unit test
node_algorithm_black. It added d_bvTypeNode as a data member to the
class and initialized it in setUp() but did not free it in
tearDown(), which set off ASan. This commit fixes tearDown() to free
d_bvTypeNode.

Marking this as major because it should fix the nightlies.
