Since #its has its(pun) own way of handling calls with a dot-notation, the full call is never passed to the resource. For example:
```ruby
describe json('file') do
its('a.b.c') { should eq 123 }
end
```
This is resolved to calling `json('file').a.b.c` and thus doesnt work as an intended `json('file').send('a.b.c'). For now use
regular its-behavior of calling `json('file').params ... its(%w{a b c}) { should ... }`.
Its' behavior must be improved.
