Site.from_hash cannot consume data generated by Site.to_h

[abunn-r7]

When attempting to import/export a site using the to/from hash methods the gem throws an error when importing.

NoMethodError: undefined method `each' for nil:NilClass
        from /home/abunn/.rvm/gems/ruby-2.2.0/gems/nexpose-1.0.0/lib/nexpose/site.rb:440:in `from_hash'
        from (irb):8
        from /home/abunn/.rvm/rubies/ruby-2.2.0/bin/irb:11:in `<main>'

This appears to be due to the Site object in the 1.0 gem changing the :addresses attribute to :included_scan_targets, but the from_hash method not being updated.

Prep Export:
# Write the site configuration to a file.
site = Site.load(nsc, site_id)
File.write("site-#{site_id}.bak", site.to_json)

Import from json export into new Site:
site_bak = JSON.parse(File.read("site-#{ARGV[1]}.bak"))
site = Site.from_hash(site_bak)
site.id = -1
# Set to use the local scan engine.
site.engine_id = nsc.engines.find { |e| e.name == 'Local scan engine' }.id
site_id = site.save(nsc)

Failure happens during:
site = Site.from_hash(site_bak)
trying to access key as symbol, but it only responses to string

For now, the solution could be telling the JSON.parse to symbolize_names
site_bak = JSON.parse(File.read("site-#{ARGV[1]}.bak”), symbolize_names: true)

[sgreen-r7]

@abunn-r7 Planning on just closing this out. Do we need to fix this in the gem or just use the solution provided? site_bak = JSON.parse(File.read("site-#{ARGV[1]}.bak”), symbolize_names: true)
