Fix durability test flakyness

Browse Source 
Summary:
It occurred that part of the durability flakyness test might be that the
same durability directory is used always. If the test is run
simultaneously on a single system, there will be interference.

This might not actually fix all the flakyness :(

I also made the `utils::RandomString` function since that's now used in
multiple places, tested it etc.
