Fix laravel-ide-helper generate:model

[keatliang2005]

This PR is attempt to fix #516, as on post #516 (comment) pointed out, it already provide the arg to not execute save.

so we can leverage that, if user id is not present, we set the method getWallet argument $save as false.

this will ensure, when authenticated user id will auto save,
when execute without any authentication for this instance, laravel-ide-helper would not execute save
