[fbl][wavl] Remove a useless and incorrect using directive.

There is no real reason for the generic node_state fetcher in WAVL
tree to have a RankType using alias.  In addition, this alias was
incorrect.  It was missing the TagType parameter for the node_state
template which caused it to incorrectly fall back on the default tag.
This would only be caught when attempting to instantiate a tree of
objects which used the ContainableBaseClasses pattern, but no default
WAVLTreeContainable mix-ins.

Also, add new tests which would have caught this in the first place,
and fix an existing test which was broken and caught by the new test
augmentations.

Test: new tests
