Fix bug in implementation of `NotExpr`. It should not implement
`compareContents()`.

This bug would not have affected correctness but it would have
affected performance because if `Expr::compare()` was called on
two structually equal `NotExpr` then its children would be
checked for structually equality twice - once in
NotExpr::compareContents()` and once in `Expr::compare()`.

This partially addresses #515 .
