Changed testing variables in init.pp

[mr-tron]

Bad logic for type validate.

Well, I'm not sure what this is for. The ability to specify either an array or a hash was added in #369.

[mr-tron]

Now if variable is hash (for example), this condition return fail('$http_cfg_append must be either a hash or array'), because:

1. http_cfg_append = {'dfffd'=>'dsfdsf'}
   2)is_hash($http_cfg_append) = true
   is_array($http_cfg_append) = false
   3)!is_hash($http_cfg_append) = false
   !is_array($http_cfg_append) = true
2. !is_hash($http_cfg_append) or !is_array($http_cfg_append)= true
   variant of fix: !is_hash($http_cfg_append) and !is_array($http_cfg_append)

The module is currently broken, as $http_cfg_append directive can't accept any value.

Well, let's 🔧 that. Thanks. 🙇
