[DRE-maint] Bug#867027: test failure: Grape::Validations::CoerceValidator coerce multiple types for primitive collections when updating ruby-hashie

[Pirate Praveen]

package: ruby-grape
version: 0.16.2-2

When updating ruby-hashie to 3.5.5 (in alioth git), the following tests
fail.

Failures:

  1) Grape::Validations::CoerceValidator coerce multiple types for
primitive collections allows singular form declaration
     Failure/Error: expect(last_response.body).to eq('["the", "other"]')

       expected: "[\"the\", \"other\"]"
            got: "#<Hashie::Array [\"the\", \"other\"]>"

       (compared using ==)
     # ./spec/grape/validations/validators/coerce_spec.rb:628:in `block
(5 levels) in <top (required)>'

  2) Grape::Validations::CoerceValidator coerce multiple types for
primitive collections allows multiple collection types
     Failure/Error: expect(last_response.body).to eq('[1, 2, 3]')

       expected: "[1, 2, 3]"
            got: "#<Hashie::Array [1, 2, 3]>"

       (compared using ==)
     # ./spec/grape/validations/validators/coerce_spec.rb:642:in `block
(5 levels) in <top (required)>'

  3) Grape::Validations::CoerceValidator coerce multiple types for
primitive collections allows collections with multiple types
     Failure/Error: expect(last_response.body).to eq('[1, 2, "true",
"three"]')

       expected: "[1, 2, \"true\", \"three\"]"
            got: "#<Hashie::Array [1, 2, \"true\", \"three\"]>"

       (compared using ==)
     # ./spec/grape/validations/validators/coerce_spec.rb:656:in `block
(5 levels) in <top (required)>'
