As the context parameter is not used and fixing it is not trivial, let's rather just drop that. Why is it not trivial? The usual select with <-ctx.Done() would not work, as ldb.gc.runC is always expected to have 1 element when the GC is not running. Also: #1151
Test fails unreliably when run with `-race` flag. As waitGC() does not work as expected, it might just continue (not block) if GC is not running already. We might end up with or without a chunk, depending on goroutine scheduling. As localstore rewrite is at the finish line and this blocks #741 => Skip.
