add $keys to the getAttributes() call to comply with laravel 5.3.17

Otherwise you get this message

ErrorException: Declaration of Delatbabel\Elocrypt\Elocrypt::getAttributes() should be compatible with Illuminate\Database\Eloquent\Model::getAttributes($keys = Array)

@delatbabel any thoughts?

I'm still trying to figure out if this breaks any earlier versions, e.g. Laravel 5.1 or 5.2.

Let me get back to you or if you run any checks against those versions then let me know.

OK unfortunately this breaks against Laravel 5.1 LTS at least. So I will have to create a separate branch for this fix.

Unless of course you can convince Taylor to backport the Laravel 5.3.17 change to earlier versions. I'm not sure why he would make such a breaking change without even notifying anyone. I can't see any release note about this change. In fact the latest Laravel 5.3 API docs don't even mention this change -- the function call is described here without the $keys array:

https://github.com/laravel/framework/blob/5.3/src/Illuminate/Database/Eloquent/Model.php#L3074

[delatbabel]

OK subsequent to the above it looks like Taylor has reverted the 5.3.17 change:

laravel/framework#15813

So I will close this PR as incorporating it will break everything. You should update to a later Laravel release that has the original change reverted.

Ah good catch. I didn't see that it was reverted. Thanks!
