Add missing brackets for function call

[gerlingsm]

Summary

Two brackets have been added around the arguments of the second scope.call_function

Additional Context

Add any additional context about the problem here.

• Root cause and the steps to reproduce. (If applicable)
• Thought process behind the implementation.

The problem here is or was that the argument was not passed correctly to the function "authz_core_config" and you then got an error message from it that an incorrect variable type was passed.
"parameter 'config' expects a Hash value, got Tuple"
thanks to @Hufschmidt for helping to find the error and solve the problem

For error reproduction it is sufficient to use "authz_core" in some way within a directory in a vhost.
For example as described in the ReadMe:

puppetlabs-apache/manifests/vhost.pp

Lines 1369 to 1392 in b9ac34c

	# * `Basic` - Specifies mod_authz_core parameters for particular directories in a virtual host directory
	# ```puppet
	# apache::vhost { 'sample.example.net':
	# docroot => '/path/to/directory',
	# directories => [
	# {
	# path => '/path/to/different/dir',
	# auth_type => 'Basic',
	# authz_core => {
	# require_all => {
	# 'require_any' => {
	# 'require' => ['user superadmin'],
	# 'require_all' => {
	# 'require' => ['group admins', 'ldap-group "cn=Administrators,o=Airius"'],
	# },
	# },
	# 'require_none' => {
	# 'require' => ['group temps', 'ldap-group "cn=Temporary Employees,o=Airius"']
	# }
	# }
	# }
	# },
	# ],
	# }

@gerlingsm can you maybe add a unit test for this to ensure that this works now?

@gerlingsm can you maybe add a unit test for this to ensure that this works now?

I will try tomorrow or early next week yes.
However, this is my first pull request for a Puppet project and I haven't dealt with unit tests before....

@bastelfreak Could you have a look? Is that sufficient?
