Change default remote_sites_path to base_path()

[lakuapik]

As issued here https://github.com/facade/ignition/issues/314, many people have problem with remote_sites_path not working as expected.

I think its the local_sites_path that they were talking about, one problem i found is when we set remote_sites_path to directory other than laravel base_path, the local_sites_path just wont work. the url fallback-ted to default and local_sites_path never used.

One simple solution i found was changing the remote_sites_path to laravel base_path instead of empty string '' or null, then only set the local_sites_path.

I have tested on facade/ignition, but not tested yet with spatie/laravel-ignition since i cannot install from packagist:
