[tor-commits] [onionoo/master] Reset sorted fingerprint blocks when setting fingerprint.

commit 54ef1a7e34659ab7941b7c2d769fd7a8d851d1a6

    Reset sorted fingerprint blocks when setting fingerprint.
    
    Previously, we'd only have calculated sorted fingerprint blocks once,
    but not after setting a new fingerprint.  We never ran into this bug,
    because we never called that setter outside of the constructor.  But
    future uses of that setter would have caused trouble.
    
    Found while writing Javadoc comments for #19613.
