MySQL configuration on startup fails when trying to set up users

[M-arcus]

Describe the bug
MySQL configuration on startup fails when trying to set up users after updating to newest devenv.lock

To reproduce

{ pkgs, lib, ... }:
{
  services.mysql.enable = true;
  services.mysql.package = lib.mkDefault pkgs.mysql80;
  services.mysql.initialDatabases = [{ name = "db"; }];
  services.mysql.ensureUsers = [{
    name = "db";
    password = "db";
    ensurePermissions = { "*.*" = "ALL PRIVILEGES"; };
  }];
  processes.entryscript.exec = ''
    ${pkgs.coreutils}/bin/sleep infinity
  '';
}

works.

But adding this breaks the devenv up command:

  services.mysql.settings = {
    mysql = {
      user = "db";
      password = "db";
      host = "127.0.0.1";
    };
  };

Error log:

10:59:42 mysql-configure.1 | mysqld is alive
10:59:42 mysql-configure.1 | ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

Version

$ devenv version
devenv: 0.6.3

Looks like it's broken again, executing mysql does not use the configured values anymore.

We really need a test for this
