TypeNotPresentException during entity augmentation
**Describe the bug**
I'm seeing Maven build failures from the package phase (and later phases) due to entity class augmentation failures.

**Expected behavior**
Jar files are created for the project.

**Actual behavior**
No jar files are created.  This is failing on an entity that is catching a `NoResultException` or a `NonUniqueResultException`.  These classes are in the dependency tree of the project, and show up in the class path and constructed class loader during the build.

**To Reproduce**
Run `./mvnw clean package` on the attached example project.

**Screenshots**
```

**Environment (please complete the following information):**
 - Output of `uname -a` or `ver`: 
`Linux **** 5.0.0-23-generic #24-Ubuntu SMP Mon Jul 29 15:36:44 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux`
 - Output of `java -version`: 
```
openjdk version "11.0.4" 2019-07-16

OpenJDK 64-Bit Server VM (build 11.0.4+11-post-Ubuntu-1ubuntu219.04, mixed mode, sharing)
```
 - GraalVM version (if different from Java): n/a (not using GraalVM)
 - Quarkus version or git rev: 0.20.0

**Additional context**
It looks like when `HibernateEnhancingClassVisitor` is constructed, it does not pass along the class loader to the new instance of `ClassWriter`.  It somehow gets a different class loader, which knows nothing about the carefully constructed class loader from Quarkus, so it throws a `ClassNotFound` exception when it processes the entity class, trying to find `NoResultException` or `NonUniqueResultException`.
