Fixed Metadata deserialization

Metadata fields 'dependencies', 'conflicting', 'providing', 'platforms' and 'replacing' are
simple Map<String, String>, where the value is a version constraint like '>= 0.0.0', but not
a Json array.

See https://github.com/opscode/chef/blob/master/chef/lib/chef/cookbook/metadata.rb for more
details about Metadata format.
