[Libguestfs] [hivex PATCH] ruby: improve test functions

[Pino Toscano]

Use better functions to check for proper values instead of assert:
- refute_nil for non-null functions
- assert_equal for checking equality

Also, make sure that the parameters for assert_equal are correct:
expected value, then got value.
