Crash on Accessing address: (nil) on UndoLog_DeleteEdge

[zimingL]

We observed a crash running RedisGraph version 2.12.10.

And this is related to #3176
I can reproduce it by running two redis pods executing queries at the same time, and some queries contain DELETE operations.
(I'll later try to provide some samples so that you could reproduce easily)

See BUG REPORT below:
