Subject: [rubygems/rubygems] Fix incorrect `gem uninstall --all` message

Currently `gem uninstall --all` shows the following incorrect message
after completion:

```
INFO:  Uninstalled all gems in
```

Now it shows something that actually makes sense like:

```
INFO:  Uninstalled all gems in /home/deivid/Code/rubygems/tmp/test_rubygems_6986/gemhome
```
