After creating new connection profile in the Select Connection Profile action/dialog, new profile does not show up in dialog list and can't be selected

1) Select a Source model and right-click select "Modeling > Set Connection Profile" action
2) Select "New..." button to launch the New Connection Profile wizard.
3) Create new CP and return to first dialog
4) New CP is Not displayed and can't be selected.

I ran into this fixing the Flat File/Text File connector use-case

Need to refresh the tree and auto-select the new CP in the tree
