SNI: Fix crash with ToolTip of type String

TeamViewer exposes ToolTip as String (which is not compliant to the spec).
This caused gBar to crash, since we assume, that the tooltip variant is
always a container (struct), which glibc doesn't like.

We now fallback to g_variant_get_string if it is not according to spec
