Provider String is empty

[Paulus]

For some providers the string is empty. This looks similar to #465 and #466 just with fsogsmd.

root@om-gta02 ~ # mdbus2 -s  org.freesmartphone.ogsmd /org/freesmartphone/GSM/Device org.freesmartphone.GSM.Network.GetStatus
( { "provider": " ", "strength": 90, "display": " ", "lac": "700F", "mode": "automatic", "code": "26201", "cid": "D441", "pdp.cid": "", "pdp.lac": "", "pdp.registration": "unregistered", "registration": "home", "act": "GSM" } )
root@om-gta02 ~ # mdbus2 -s  org.freesmartphone.ogsmd /org/freesmartphone/GSM/Device org.freesmartphone.GSM.Network.ListProviders
( [ ( "current", " ", " ", "26201", "GSM" ), ( "forbidden", "o2 - de", "o2 - de", "26207", "GSM" ), ( "forbidden", "E-Plus", "E-Plus", "26203", "GSM" ), ( "forbidden", "Vodafone.de", "Vodafone", "26202", "GSM" ) ] )
root@om-gta02 ~ # mdbus2 -s  org.freesmartphone.ogsmd /org/freesmartphone/GSM/Device org.freesmartphone.GSM.SIM.GetSimInfo

I'll implement this by communicating with fsodatad.
