Minimal changes make IDEA 2023.2 work out-of-box

Fix insertAuxInitializer may cause inconsistent stack height problem

Update tutorial.html: `javassist.util.HotSwapper`

Correct maven-compiler-plugin JDK version for IDEA import Compiler bytecode version.

Remove JvstTestRoot's constructor, otherwise IDEA cannot show Run icon aside testMethod.
Another way is adding suite() static method to those classes.

Now we can clone and open project with IDEA 2023.2. Debug single test case with IDEA is very useful.

Usually, constructor only load super class's constructor's init params into stack.
After this() or super() called, stack will be empty. If so, we insertAuxInitializer
right after this() or super() can reuse max stack size if it enough.

But, there is some weird class out there, their constructors load all in-constructor
init field value into stack before this() or super() call. In this case,
after this() or super() call, stack is not empty, even maybe full.

In summary, insertAuxInitializer should increase MaxStack anyway.

The code path is fixed.

Fix MemberResolver.lookupMethod bug when super class has more precise…

DUP usually come after NEW, but not necessary.

#453

When onlyExact=false and super class have a more precise match,
it should not return with current class's maybe result.

New added testSuperCall reveals the problem.

fixes Issue 462 (In Java21, the ConstPool API throws NPE for MethodParameters attributes without parameter names)

A standard *new* construct bytecode will generate like:

```
new okhttp3/OkHttpClient
dup
invokespecial okhttp3/OkHttpClient <init> ()V
astore 1
```

but a few part of compiler will generate no-standard bytecode like:

```
new okhttp3/OkHttpClient
dup
astore 1
invokespecial okhttp3/OkHttpClient <init> ()V
```
which will cause javassist build stack error.
