Allow Reset Layout Button to work on Collapsed Tables

In a complex semantic model, it is often desireable to get the smallest layout possible.  This is accomplished by collapsing all the tables to show only the join keys.  However, right now, if you click the "Reset Layout" button in the lower right corner, it expands all the tables before resetting the layout.  If I have all the tables collapsed, I want the reset button to lay out the semantic model with the tables collapsed.
