ims-pdn-up: an empty profile list is the modem coming up, not a modem without ims

Browse source 
On a cold boot the profile-list query can succeed while ModemManager is
still enabling the modem and return no profiles at all; the lookup then
read "no ims profile" and fell back to the APN-string request, the one a
walled carrier refuses (Fairphone 6, index 2 present a minute later).
Treat a list without any profile entry like a failed lookup and retry it
after the registration wait; a list with entries but no ims APN still
falls back to the APN string.
