Sam Minnée 5bfc37ff4b FIX: Use Hierarchy::prepopulateTreeDataCache() in CMS (#2266)
* FIX: Use Hierarchy::prepopulate_numchildren_cache in tree-generation

Only relevant if https://github.com/silverstripe/silverstripe-framework/pull/8380 is avialable,
however coded defensively so it can be merged before that PR if needs 
be.

See https://github.com/silverstripe/silverstripe-framework/issues/8379

* FIX: Use Hierarchy::prepopulateTreeDataCache() in CMS.

Requires https://github.com/silverstripe/silverstripe-framework/pull/8395

* Cache tree_class instead of assuming it will always be SiteTree.
