Some improvements to TestVolumesInspect
Some improvements to TestVolumesInspect

Some improvements in this test;

- use the volume-information that's returned by VolumeCreate as "expected"
- don't use an explict name for the volume, as it was only used to reference
  the volume for inspection
- improve the test-output on failure, so that "expected" and "actual" values
  are printed

Without this patch applied;

    === RUN   TestVolumesInspect
    --- FAIL: TestVolumesInspect (0.02s)
     	volume_test.go:108: assertion failed: false (bool) != true (true bool): Time Volume is CreatedAt not equal to current time
