Misleading error message if there is error inside else branch

[kubouch]

Describe the bug

If there is an error in the else branch, the produced error is very unhelpful.

How to reproduce

> if false { 'a' } else { $foo }
Error: nu::parser::parse_mismatch (link)

  × Parse mismatch during operation.
   ╭─[entry #40:1:1]
 1 │ if false { 'a' } else { $foo }
   ·                       ────┬───
   ·                           ╰── expected one of a list of accepted shapes: [Block, Expression]
   ╰────

Compare to the output when there is an error in the if branch:

> if true { $foo } else { 'a' }
Error: nu::parser::variable_not_found (link)

  × Variable not found.
   ╭─[entry #41:1:1]
 1 │ if true { $foo } else { 'a' }
   ·           ──┬─
   ·             ╰── variable not found
   ╰────

Expected behavior

> if false { 'a' } else { $foo }
Error: nu::parser::parse_mismatch (link)

  × Parse mismatch during operation.
   ╭─[entry #40:1:1]
 1 │ if false { 'a' } else { $foo }
   ·                         ──┬─
   ·                           ╰── variable not found
   ╰────
