In the not-too-likely scenario where we successfully created a hash table entry for a TS dictionary, but then failed to make a small memory context for it, we left the hash entry in existence but with a garbage value for dictCtx. This confused the code the next time through, leading to a crash. Rearrange things so that we leave the hash entry in a well-defined state with dictCtx == NULL, and then the next try knows it still needs to make a memory context.
