revlog.revision(): don't use nullrev as the default value for the cache

I is probably a bug if the deltachain computation think there was a cache hit
at nullrev. Use None instead, this will never trigger a cache hit.

try:
    import coverage
    if hasattr(coverage, 'process_startup'):
        coverage.process_startup()
except ImportError:
    pass
