Remove +1 stripping from numbers in modem scripts

Note prefix stripping was unreliable because any +1XX number would break things.
The advice should be to always dial with +1 / international prefixes and store
contacts in your contacts.tsv with international codes; this way we avoid any
duplicate errors since we can be assured things in mmcli always come back w/
international prefixing automatically.
