Jean Boussier bb1c3418d0 Add more assertions in `test_uplus_minus`
Not along after 1b830740ba CI
started to rarely fail this test:

```
TestString#test_uplus_minus: Test::Unit::AssertionFailedError: uminus deduplicates [Feature #13077].
  1) Failure:
TestString#test_uplus_minus [/tmp/ruby/src/trunk/test/ruby/test_string.rb:3368]:
```

It's unclear what is going on, but one possibility is that
`"bar".freeze` might no longer compile correctly.

Another possibility is that another test redefine `String#freeze`,
causing `opt_str_freeze` to no longer return an `fstring`.

What is Ruby?

Ruby is an interpreted object-oriented programming language often used for web development. It also offers many scripting features to process plain text and serialized files, or manage system tasks. It is simple, straightforward, and extensible.

Features of Ruby

  • Simple Syntax
  • Normal Object-oriented Features (e.g. class, method calls)
  • Advanced Object-oriented Features (e.g. mix-in, singleton-method)
  • Operator Overloading
  • Exception Handling
  • Iterators and Closures
  • Garbage Collection
  • Dynamic Loading of Object Files (on some architectures)
  • Highly Portable (works on many Unix-like/POSIX compatible platforms as well as Windows, macOS, etc.) cf. https://docs.ruby-lang.org/en/master/maintainers_md.html#label-Platform+Maintainers
