modem-helpers: Consider minimum ID when choosing best profile

+CGDCONT? may list profiles with IDs that are illegal to write, i.e.
+CGDCONT=? returns a minimum ID larger than some of the existing
profiles. E.g. for Fibocom L610-EU, +CGDCONT=? returns

+CGDCONT: (1-7),"IP",,,(0-3),(0-4)
+CGDCONT: (1-7),"IPV6",,,(0-3),(0-4)
+CGDCONT: (1-7),"IPV4V6",,,(0-3),(0-4)
+CGDCONT: (1-7),"PPP",,,(0-3),(0-4)
+CGDCONT: (1-7),"Non-IP",,,(0-3),(0-4)

while the default EPS bearer is established at profile 0:

+CGDCONT: 0,"IP","xxx","xxx.xxx.xxx.xxx",0,0
