Update vendor feature spec to system spec

[jenpen]

Summary:
Rails 5.1 introduced "System Tests", the brave new world of automated testing in Rails. It seems like this has been refined quite a bit and will become more prevalent in Rails 6.0. We'd like to get ahead of the curve on this.

Task:
We need to convert /spec/features/vendor_spec.rb from a feature spec to a system spec. There are 4 steps to this:

• Create a similarly named file in the spec/system directory. For example if the file was called happy_spec.rb it would be called happy_system_spec.rb in the new directory.
• Set each spec’s type as type: :System
• Use RSpec.describe to define system specs, instead of RSpec.feature
• Replace the scenario alias in previous feature specs with the standard it syntax

Two files have already been converted that you can use as examples -- the account_system_spec.rb spec and the adjustment_system_spec.rb spec. You can also see the original feature files at account_spec.rb spec and adjustment_spec.rb spec.

More information on system specs can be found below.
