      Sometimes a signal isn't delivered properly.

      Debug output when it is delivered:

      QDEBUG : TestOfonoModemManager::testOfonoModemManagerAddRemove() 
QDBusConnectionPrivate(0xa013fe0) got message (signal): 
QDBusMessage(type=Signal, service="org.freedesktop.DBus", 
path="/org/freedesktop/DBus", interface="org.freedesktop.DBus", 
member="NameOwnerChanged", signature="sss", contents=("org.ofono", "", 
":1.125") )

QDEBUG : TestOfonoModemManager::testOfonoModemManagerAddRemove() 
QDBusConnectionPrivate(0xa013fe0) Updating name "org.ofono" from "" to 
":1.125"

QDEBUG : TestOfonoModemManager::testOfonoModemManagerAddRemove() 
QDBusConnectionPrivate(0xa013fe0) got message (signal): 
QDBusMessage(type=Signal, service=":1.125", path="/", 
interface="org.ofono.Manager", member="ModemAdded", signature="oa{sv}", 
contents=([ObjectPath: /phonesim], [Argument: a{sv} {"Online" = 
[Variant(bool): false], "Powered" = [Variant(bool): false], "Interfaces" 
= [Variant(QStringList): {}], "Features" = [Variant(QStringList): {}]}]) )

      And when it's not delivered:

      QDEBUG : TestOfonoModemManager::testOfonoModemManagerAddRemove() 
QDBusConnectionPrivate(0xa013fe0) got message (signal): 
QDBusMessage(type=Signal, service="org.freedesktop.DBus", 
path="/org/freedesktop/DBus", interface="org.freedesktop.DBus", 
member="NameOwnerChanged", signature="sss", contents=("org.ofono", "", 
":1.123") )

QDEBUG : TestOfonoModemManager::testOfonoModemManagerAddRemove() 
QDBusConnectionPrivate(0xa013fe0) got message (signal): 
QDBusMessage(type=Signal, service=":1.123", path="/", 
interface="org.ofono.Manager", member="ModemAdded", signature="oa{sv}", 
contents=([ObjectPath: /phonesim], [Argument: a{sv} {"Online" = 
[Variant(bool): false], "Powered" = [Variant(bool): false], "Interfaces" 
= [Variant(QStringList): {}], "Features" = [Variant(QStringList): {}]}]) )

QDEBUG : TestOfonoModemManager::testOfonoModemManagerAddRemove() 
QDBusConnectionPrivate(0xa013fe0) Updating name "org.ofono" from "" to
