"Show in remote system explorer" action is available when several running instances are selected, but it only shows the first on in the RSE

1) make sure you have a cloud with several running instances (ex. on a mock deltacloud locally) 2) select several of them in the instances view 3) choose "show in remote system explorer" in the context menu Result: RSE is opened for the first (of the selected) instances Expected: the action should only be available if a single instance is selected OR open all of them in RSE
