Made parameter package_provider optional.

[schkovich]

In addition to making parameter package_provider optional I wrote basic tests for related classes.
Note change in spec/classes/php_spec.rb on line 5. Example was failing with

TypeError: no implicit conversion of Symbol into Hash
/home/goran/.gem/ruby/2.2.0/gems/rspec-puppet-2.0.0/lib/rspec-puppet/matchers/include_class.rb:7:in `block (2 levels) in <module:ManifestMatchers>'
./spec/classes/php_spec.rb:6:in `block (2 levels) in <top (required)>'

include_class matcher was deprecated in rspec-puppet 1.0 and later on removed. As advised I used contain_class instead.
close #131

please note that i've done that in commit 2 of #116, which i'd still really like to see some reviews for!

@igalic I am not following you. You are referring to de013c1? I can't see any overlapping with with a0dab92. :(

👍 This should fix my issue.

[igalic]

@schkovich gosh you're right, i'm sorry
