[TASK] Use correct icons for TCA type select with renderType selectTree

With the introduction of the new icon API the icons shown in the TCA
selectTree broke. This patch changes the tree js so it can handle the
new icon API.

The "old fashioned" fallback icons in tree view of e.g. categories
are replaced with current style of icons from the page tree.
