Model::delete() should not be called statically

[junk123321]

运行php.exe artisan migrate，提示Non-static method Illuminate\Database\Eloquent\Model::delete() should not be called statically
修改以下就可以了

1. 把vendor\wanglelecc\laracms-framework\database\migrations\2018_02_25_170926_seed_roles_and_permissions_data.php的User::delete();改成User::where(DB::raw(1), 1)->delete();
2. 把vendor\wanglelecc\laracms-framework\database\migrations\2018_03_04_174004_seed_slide_and_block_and_files_data.php的
   File::delete();
   Slide::delete();
   Block::delete();
   改成
   File::where(DB::raw(1), 1)->delete();
   Slide::where(DB::raw(1), 1)->delete();
   Block::where(DB::raw(1), 1)->delete();
