Bug #22740: create_resources() fails with empty hash under Ruby 1.9.3

----------------------------------------
Due to the change in the way strings are handled in relation to the enumerable
module in Ruby 1.9.3 vs Ruby 1.8.7
zachary-puppetbot :: ~/testing/1.8.7 % pry
[1] pry(main)> 'foo'.each
=> #<Enumerable::Enumerator:0x1031c6f20>
zachary-puppetbot :: ~/testing/1.9.3 % pry
[1] pry(main)> 'foo'.each
NoMethodError: undefined method `each' for "foo":String
from (pry):1:in `__pry__'
there is a regression in the `create_resources()` function.
When Puppet is run with Ruby 1.8.7, the following code runs without error, with
`$foo` undefined:
create_resources(user, $foo)
Under Ruby 1.9.3, the following error occours during a run:
Error: Could not retrieve catalog from remote server: Error 400 on
SERVER: undefined method `each' for "":String at
/etc/puppetlabs/puppet/manifests/site.pp:45 on node
pe-301-master.puppetdebug.vlan
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run
Given that this is an inherent change in ruby's behavior, it might be
impossible (or unwise) to restore the original behavior. That being said, we
should at least catch the error, since the above is not very helpful to Puppet
users.
