Fix "ConsulAcl" provider when specified "id" doesn't exist

[legal90]

If the token ID doesn't exist, Diplomat::Acl#info returns an empty array and it causes an error:

           ================================================================================
       Error executing action `create` on resource 'consul_acl[vault]'
           ================================================================================

           NoMethodError
           -------------
           undefined method `select!' for nil:NilClass

           Cookbook Trace:
           ---------------
           /tmp/kitchen/cache/cookbooks/consul/libraries/consul_acl.rb:89:in `up_to_date?'
           /tmp/kitchen/cache/cookbooks/consul/libraries/consul_acl.rb:56:in `action_create'

This PR fixes that issue.
