revlog: update pure nodecache start lookup offset on insertion

test-storage.py is failing in pure builds because the population of the node
cache isn't accounting for the new starting offset after a revlog insertion.

This commit updates the node cache start offset to account for insertions.

I'm not 100% convinced this is the ideal solution. But it works and seems
correct.
