fix subscribers parameter in sensu_check

[kam1kaze]

Hi,

Today I faced with the issue when tried to define subscribers for existed check:

Error: /Stage[main]/Lmm_sensu::Checks/Lmm_sensu::Checks::Elasticsearch[***]/Sensu::Check[***]/Sensu_check[***]/subscribers: change from  to lmm failed: undefined method `sort' for nil:NilClass

it is related to such part of code:

lib/puppet/type/sensu_check.rb

   81   newproperty(:subscribers, :array_matching => :all) do
   82     desc "Who is subscribed to this check"
   83     def insync?(is)
>  84       is.sort == should.sort
   85     end
   86   end
