Removed rspec patches since it turns out we don't actually need them

for example:

instead of our way: describe SomeClass, iso_id: '1.2.3.4' do
we can do: describe SomeClass, 'iso: 1.2.3.4' do

for examples we can just do:

it "should do this, iso: 1.2.3.5" do

Pity I spent time on implementing this, oh well.
