[rubygems/rubygems] Fix test warnings

Browse Source 
Since `rake package` started printing to stdout by default, we get these
warnings printed when running rubygems tests:

```
$ rake
Run options: --seed 6097

```

The reason is that, although these tests wrap the
`Rake.application["package"].invoke` with a `capture_io` block, the rake
application initialization happens outside of this block, and a copy of
`$stdout` is saved in there, and that's where the task prints. So the
`capture_io` `$stdout` and `$stderr` dance is not effective.

To fix, we move the `Rake` application initialization inside the
`capture_io` block.
