Fix compilation error when building single graph_editor crate (#3319)

Browse Source 
@akavel spotted a compilation error, when building test for graph_editor crate. The cause was that:
* prelude without serde still added serde derivatives in im_string_newtype
* and the graph_editor needs serde from prelude anyway (because it wants to have serializable ImStrings).
