Reinstate deleted tests

These tests were removed and one of them reimplemented as a unit test in 8cd8df57f. However, the second one was not reimplemented. This test demonstrates that when customization fails, the VM orchestrator leaves the VM in a half-finished state with no error message, i.e. it fails silently to do the rest of the customization. This test was highlighting that bug.

It was not reimplemented as a unit test because the plan was to fix the bug as the next piece of work - however, that person was then off sick and then moved on to another team. Reinstating it here so that at least it is tested.

Revert "minimizing time taken by storage profile test"

This reverts commit 6a957dec2987c7fa0211b5354388da8e83a3b270.

The reason for doing this is that I am reinstating a test that relies on this data. See 628e3402b for details.

Once that is addressed, this should be reverted again, because this does add ~2 minutes to the tests.
