Current behavior

Expected behavior

We should refactor the forRoot method to not have the first param uri. And make the URI non-optional in the MongooseModuleOptions. Then we could safe this if statement. This would also have the advantage that the forRoot method and the MongooseModuleAsyncOptions have the same params. Which feels better for me.

Minimal reproduction of the problem with instructions

None.

What is the motivation / use case for changing the behavior?

Better alignment of params. This would introduce breaking changes.
