* Fix storage/remote.pool interned refs count and flaky test
I saw TestIntern_MultiRef_Concurrent failing on a different PR saying 'expected refs to be 1 but it was 2'.
I took a look, and it definitely can be racy, especially with a time.Sleep() of just 1ms.
I'm fixing that by explicitly waiting until it has been released, and by repeating that 1000 times, otherwise it's just a recipe for a future flaky test.
OTOH, I also took a look at the implementation and saw that we were not holding the RLock() when increasing the references count, so when releasing there was a race condition for the cleanup, I fixed that by holding RLock() while increasing the references count.
