If `variablesReference` is 0, it's treated as not provided as it's only
meaningful if its value > 0. This is also how `request_variables` and
`request_setVariable` handle it.
The spec
https://microsoft.github.io/debug-adapter-protocol/specification#Types_Variable
says: "If `variablesReference` is > 0, the variable is structured ...".
