Test if a snapshot name already exists

Browse Source 
This fix random test failure when testing snapshots. It
seem under high load sometimes the previous snapshot folder
was not visible on disk. Perhaps a test isolation issue but
I don't see how.

But in any case it's better to test if the name is not already
use.

Fix #1118
