fix: closes #421
...
The unifier used to implement the `cases` tactic should not discard
equations of the form `x = t` and `t = x` using proof irrelanvance.
The new test demonstrates the issue. The unifier was reaching the
state
```
x : Conw Con.nil
|- x = Conw.nilw -> x = Conw.nilw
```
and discarding the equality instead of substituting `x`
because `x` and `Conw.nilw` are definionally equal due to
proof irrelevance.
@javra Do you have more complicated examples that were being
affected by this issue?

@Kha I marked the corresponding methods as `protected`.
I currently can't stand `throw_error`, and I am optimistic about
server highlighting feature you are working on :)

@Kha I think this one is a good change, there is no real reason for

feat: add introNP and intro1P
...
Versions of `introN` and `intro1` that preserve the binder name.
They are used to implement the idiom: "revert", do something, re-"intro"-tuce
Before this commit `introNP mvarId n` was `intro1 mvarId n [] false`.
