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.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
