fix(frontends/lean/calc_proof_elaborator): bug when inserting symmetry proofs for heq, fixes #286
...
The problem was that heq type is
Pi {A : Type} (a : A) {B : Type} (b : B), Prop
The calc_proof_elaborator was assuming that (a : A) (b : B) were the
last two arguments in any relation supported by calc.
The fix is to remove this assumption.

Given (H_1 : a = a), we have that

This is not exclusive to equality.
It applies to any inductive datatype in Prop, containing only one
constructor with zero "arguments" (we say they are nullary).
BTW, the restriction to only one constructor is not needed, but it is
does not buy much to support multiple nullary constructors since Prop is
proof irrelevant.
