c27395ddc8 eval: Fix QuickBuild failures
Compiler used by one VM in QuickBuild has found a number of false positives.
Everything is fine on travis.

List of failures:

From [QuickBuild][1], build [7429][2]:

    14:38:19,945 WARN  - /home/quickbuild/buildagent/workspace/root/neovim/pull-requests-automated/src/nvim/eval.c: In function ‘assert_bool’:
    14:38:19,945 WARN  - /home/quickbuild/buildagent/workspace/root/neovim/pull-requests-automated/src/nvim/eval.c:7551:40: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
    14:38:20,058 WARN  - cc1: all warnings being treated as errors

. This is not making much sense (7551:40 is `!=` in `{SpecialVarValue} !=
({bool}?{SpecialVarValue}:{SpecialVarValue})`), but this error is present.

---

Also fail from [build][3] [4930][4]:

    15:47:00,853 WARN  - /home/quickbuild/buildagent/workspace/root/neovim/pull-requests-automated/src/nvim/eval/encode.c: In function ‘encode_read_from_list’:
    15:47:00,853 WARN  - /home/quickbuild/buildagent/workspace/root/neovim/pull-requests-automated/src/nvim/eval/encode.c:258:30: error: conversion to ‘char’ from ‘int’ may alter its value [-Werror=conversion]

, pointing to `:` in `{char} = ({char} == {const} ? {const} : {char})` where
`{const}` is character constant like `'\n'`. I have no idea where exactly it saw
conversion, so simply casted everything to (char).

---

[Build][5] error:

    08:32:03,472 WARN  - /home/quickbuild/buildagent/workspace/root/neovim/pull-requests-automated/src/nvim/eval.c: In function ‘tv_equal’:

d4106f6df3 shada: Make sure that NIL and EXT values can also be parsed back
Note: currently they are both *dumped*, but parsing them produces an error. This
is inappropriate: variables should either be skipped with error message when
dumping or should be read back properly.

It also appears that I did not have test for “has wrong variable value type”
error, so nothing got removed from errors_spec.
