Add analytics to track “broken” inspector state

[CoderDake]

• empty tree (one already kind of exists for this state - clicking refresh on an empty tree)
• when a tree loads with one node [root] this is an indication that there are not pub roots set
• ask Jacob for others?
• see how badly things go if you’re paused at a breakpoint
• When firstInspectorTreeLoadCompleted is done check if root is there and tree empty, log error them
