refactor(kernel/expr): remove 'null' expression, and operator bool for expression

This commit also fixes several bugs due to the use of 'null' expressions.

fix(library/fo_unify): unify (?f ?x) with (g a b)

We flat applications. So, (g a b) is actually ((g a) b).
So, we must be able to unify (?f ?x) with (g a b).
Solution:
?g <- (g a)
?x <- b
