Replace usage of hagrid::web::tests::common::assert::check_response() with hagrid::routes::tests::common::assert::response() to remove code duplication in tests.

Changes:
- Replace usage of hagrid::web::tests::common::assert::check_response()
  with hagrid::routes::tests::common::assert::response() to remove code
  duplication in tests.
- Refactor hagrid::web::tests::check_response() tests to use
  assert::response() helper.
- Take &str instead of &'static str as present_page_text argument in
  assert::response() helper. This was a bug. It affected reusability of
  the assertion helper function.
