Revert disabling of eSIM wipes/retains.

This is a revert of change I414a16cde11e76ccc390e7a63a6803f5b402fe78.
As an additional safety latch, we bypass all logic (either wipe or
retain) if the eSIM has never been provisioned. An unprovisioned eSIM
cannot possibly have profiles - indeed, we don't show the "Wipe eSIM"
checkbox in this case - so there's no reason to tell the LPA to retain
them.
