View not automatically updating when switching between dataset nodes via search only

[davetsay]

Describe the defect
#135 fixed updating views when switching between objects via search. However, this only fixed user created objects, not dataset nodes. This is an edge-case and a workaround exists.

Expected behavior
Dataset nodes should be navigatible by search as well

Steps To Reproduce

1. Go to a dataset node using a plot view
2. Go to search field, then type the name of a dataset node that does not have a plot view, ex. an EVR
3. Search result displays as a pop-up window (directory tree under the searched name doesn't seem to be updated)
4. Click the node name in the pop-up window
5. Title changed to the node name, but the view stays as a plot view.

Workaround
Use tree to navigate to node. Search can still be used to locate the node in the tree structure.
