tests: explicitly enable old "should" syntax to fix deprecation warnings (#92)

> Deprecation Warnings:
>
> Using `should` from rspec-expectations' old `:should` syntax without
> explicitly enabling the syntax is deprecated. Use the new `:expect`
> syntax or explicitly enable `:should` with `config.expect_with(:rspec) {
> |c| c.syntax = :should }` instead. Called from
> …/vim-python-pep8-indent/spec/indent/indent_spec.rb:141:in
> `block (3 levels) in <top (required)>'.
