Replace deprecated should

This replaces usage of `should` by `expect` according to the following
deprecation warning.

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.
