Waiver file of csv format not working with --filter-waived-controls option.

[Nik08]

Describe the problem

Tried running inspec profile with following command:

bundle exec inspec exec test/fixtures/profiles/waivers/basic --waiver-file test/fixtures/profiles/waivers/basic/files/waivers.csv --filter-waived-controls

Got exception:

inspec/lib/inspec/profile.rb:264:in `block in filter_waived_controls': undefined method `keys' for "control_id,justification,run,expiration_date,,, 03_waivered_no_expiry_ran_passes,Sound reasoning,TRUE,,,, 04_waivered_no_expiry_ran_fails,Unassailable thinking,TRUE,2077-11-10T00:00:00Z,,, ,,,,,, 05_waivered_no_expiry_not_ran,Sheer cleverness,FALSE,,,, 06_waivered_expiry_in_past_ran_passes,Necessity,TRUE,,,, 14_waivered_expiry_in_future_z_not_ran,Lack of imagination,FALSE,2077-11-10T00:00:00Z,,, random contorl id with no data,,,,,,random data in csv!":String (NoMethodError)

Possible Solution

Needs handling of different file formats in this logic of filter_waved_controls on line profile.rb:258
