[bug] symbol imports are not exported like module imports

Attempting to use `Object` from `love` results in an error
```py
# love/types.wu
Object: struct {}

# love/init.wu
import types { Object }

# main.wu
import love

asd : fun() -> love Object {
    new love Object {}
}
```
error:
```
wrong: no such module member `Object`
     --> main.wu
      │
    3 │ asd : fun() -> love Object {
      │                     ^^^^^^
```
