GPL-2.0-only detection rather than Apache-2.0

### Description

I use ORT that uses ScanCode v3.2.1rc2.
I scan a project that has a transitive dependency on Maven:org.wildfly.common:wildfly-common:1.5.2.Final.

The result of the scan show a wrong GPL-2.0-only detection in the pom.xml of wildfly-common.

Here is a extract of the report:

I had done another scan with an older version of ORT with ScanCode 3.0.2, and there was no GPL-2.0-Only detected in the POM

### How To Reproduce

> Tell us how to reproduce the issue.
With ScanCode in version : "3.2.1-rc2",
With the configuration : "--copyright --license --ignore *.ort.yml --info --strip-root --timeout 300 --ignore HERE_NOTICE --ignore META-INF/DEPENDENCIES --ignore **/test/** --ignore **/tests/** --ignore **/__tests__/** --ignore **/qunit/** --ignore spring-boot-tests/** --ignore doc/** --ignore docs/** --ignore documentation/** --ignore documentations/** --ignore demo/** --ignore **/example/** --ignore **/examples/** --ignore **/sample/** --ignore **/samples/** --ignore changelog.txt --json-pp"

Do a scan on a project that has a dependency on Maven:org.wildfly.common:wildfly-common:1.5.2.Final

### System configuration

> For bug reports, it really helps us to know:

* What OS are you running on? (Windows/MacOS/Linux) : Linux (Docker)
* What version of scancode-toolkit was used to generate the scan file? : 3.2.1-rc2
* What installation method was used to install/run scancode? (pip/source download/other) : With ORT Docker Image
