Refresh subscriptions in EuiccCardController.

Refresh embedded subscriptions after successfully resetting profiles
before returning a result. So LPA can switch back the physical slot
after reset is done.
Do the refresh on the success delete, sucess reset and success download
cases (loadBoundProfile).
If an OEM uses both EuiccController and EuiccCardController, the time
impact of the double refresh is small.
