The current test assumes that collie fixes replicas using the first one, but
it's no longer correct since 'vdi check' recovers replicas in parallel now.
Then we can get the following two kinds of tests and both are correct:

* if collie updates the 2nd and 3rd replica with the 1st one
    [snip]
    finish check&repair test
    finish check&repair test
    fixed replica 7c2b2500000001
    fixed replica 7c2b2500000001
    

* if collie updates the 1st replica with 2nd (or 3rd) one
    [snip]
    finish check&repair test
    finish check&repair test
    fixed replica 7c2b2500000001
    hello

To get a unique output, this series removes the duplicate
'fixed replica 7c2b2500000001' with 'uniq', and removes 'hello'
by dropping 'collie vdi read' from the test.

Thanks,
