RouterModule wrongly setting module metadata when child.path is empty string #15332
Description
Is there an existing issue for this?
- I have searched the existing issues
Current behavior
I've created a reproduction example with the readme detailing the issue here: https://github.com/gentunian/nestjs-router-module-bug-children-path-empty-string
TL&DR
The RouterModule won't set the MODULE_PATH metadata correctly to the module being passed when the path is an empty string. Instead, it will set the metadata to an object, that is the { path: '', module: <module> } object.
Minimum reproduction code

Steps to reproduce

Expected behavior
It's expected that RouterModule would set the appropriate MODULE_PATH metadata to the module. In this case, the MODULE_PATH would be the flattened one.
