[path_provider] Fix handling of null application ID (#4606)

The lookup of application ID was handling `null` (Dart null), but not
`nullptr` (Dart representation of a C null pointer), so was throwing an
exception in applications without an application ID.

This includes the `shared_preferences_linux` example application, so
this fixes tree breakage.
