lib/storage: Fix flaky test: TestStorageRotateIndexDB (#7267)
This commit fixes the TestStorageRotateIndexDB flaky test reported at:
#6977. Sample test failure: https://pastebin.com/bTSs8HP1

The test fails because one goroutine adds items to the indexDB table
while another goroutine is closing that table. This may happen if
indexDB rotation happens twice during one Storage.add() operation:
-  Storage.add() takes the current indexDB and adds index recods to it
- First index db rotation makes the current index DB a previous one
(still ok at this point)
- Second index db rotation removes the indexDB that was current two
rotations earlier. It does this by setting the mustDrop flag to true and
decrementing the ref counter. The ref counter reaches zero which cases
the underlying indexdb table to release its resources gracefully.
Graceful release assumes that the table is not written anymore. But
Storage.add() still adds items to it.

The solution is to increment the indexDB ref counters while it is used
inside add().
The unit test has been changed a little so that the test fails reliably.
The idea is to make add() function invocation to last much longer,
therefore the test inserts not just one record at a time but thouthands
of them.

To see the test fail, just replace the idbsLocked() func with:

```go
unc (s *Storage) idbsLocked2() (*indexDB, *indexDB, func()) {
       return s.idbCurr.Load(), s.idbNext.Load(), func() {}
}
```
