Major - P3 From sueloverso, split out from WT-3888.
Here's a CONFIG that hit a similar prev issue with a slightly different error message. This hit while I was testing something else and hit after 25 iterations. A second attempt on the same binary is still running after 1100 iterations (sadness). I was running this on my WT-3854 branch so it does not contain any of the lookaside changes from WT-3766. I did pull in the latest develop changes this morning however.
The error:
t: FAILED: nextprev/1193: incrementing || cmp > 0 || (cmp == 0 && tinfo->key->size > key.size): WT_CURSOR.prev returned {0000007725.13/opqrstuvwxyzabcd} then {0000009572.00/opqrstu}
