fix(java): resolve issue with resolving classes in JavaTypeUtil

The `resolveByType` function in `JavaTypeUtil.kt` was not correctly resolving classes when the `outputType` is a `PsiClassReferenceType`. This was due to a bug where the `outputType.resolve()` was being called multiple times. This commit fixes the issue by storing the resolved class in a variable and using it for comparison and assignment. Additionally, the error message in `JavaWriteTestService.kt` was not correctly interpolating the `parentDirPath` variable. This commit fixes the issue by using string interpolation to correctly display the error message.
