Wind d7014e671d use command: Don't create a variable with empty record if it doesn't define any constants (#14051)
# Description
Fixes: #13967

The key changes lays in `nu-protocol/src/module.rs`, when resolving
import pattern, nushell only needs to bring `$module` with a record
value if it defines any constants.

# User-Facing Changes
```nushell
module spam {}
use spam
```
Will no longer create a `$spam` variable with an empty record.

# Tests + Formatting
Adjusted some tests and added some tests.
