Let modules manage their own symbol in their parent scope

[sergisiso]

With #2596 Routines manage their symbol in the parent scope (attaching, detaching, renaming the routines affects their scope), modules should have the same behaviour. @LonelyCat124 I guess we can use the same Node functionality now?

Yeah - I assume we can use an update_parent_symbol_table implementation to do something with this.
