Convert cosmoz-treenode-navigator to haunted/lit.

[megheaiulian]

Convert the cosmoz-treenode-navigator component to haunted.

cosmoz-treenode-navigator has the following structural components/parts:

• path - the node/tree path
• input - used as query text to search for nodes -> use cosmoz-input instead
• list - a iron-list elemenet to show a virtualized list of nodes -> just render them all / not virtualized
• a retry button - to search globally -> use a simple html button element.

Conversion approach:

1. Extract as much code as possible in pure functions (e.g. _normalizeNodes, _getNode)
2. create a TreeNodeNavigator function/component and convert the template
3. write a useTreeNodeNavigator() function linking all the pure functions and render related code
