Modify editDashboard not mangle the graph records just enough that clone graph doesn't work.

Easiest method was to put the results into the same format that loading dashboards uses and invoke refreshGraphs.

This also correct the issue of editDashboard removing automatic titles for single-target graphs and places default sized placeholders for the graphs when they are loading.
