tests: fix asyncio usage in storage_lvm.TC_01_ThinPool

Both vm.create_on_disk() and vm.start() are coroutines. Tests in this
class didn't run them, so basically didn't test anything.

Wrap couroutine calls with self.loop.run_until_complete().

Additionally, don't fail if LVM pool is named differently.
In that case, the test is rather sily, as it probably use the same pool
for source and destination (operation already tested elsewhere). But it
isn't a reason for failing the test.
