Pressing "back" after "Switch provider" adds an EIP Fragment to Dashboard
Pressing the "back" button from ConfigurationWizard, when reached through "Switch provider" menu item, adds an EIPServiceFragment to the Dashboard.
This fragment is added dynamically, so one of the "create" or "resume" methods is adding it, even though the Activity and View are still intact.
Add a check for the Fragment before adding it in Dashboard's methods.
