message: Fix the naming of _any_variable_initialized
  This might be a very small issue, though the naming
  `_any_variable_initalized` seems to be a typo (`initalized` -> `initialized`).
  As this is
  an interanl function so renaming should be safe. This fix
  change the naming to `_any_variable_initialized`
