AemPackageConverterTest: Switch back to older wcm.io handler version affected by SLING-12197

[stefanseifert]

Small addendum to #220, issue #222:

• SLING-12197 - Fix lacking repoinit statements #220 includes a content package for testing with wcm.io Handler 2.x versions, which already include a workaround for SLING-12197, by explicitly defining a nodetype for the affected folders like {{/apps/wcm-io/handler/link/components/global/include}}
• although this does not directly inflict with the test for repoinit statements, it's better to test against older 1.x version of wcm.io handler which do not include this workaround

this PR contains an updated content package with older versions of:

• io.wcm.handler.commons-1.5.0.jar
• io.wcm.handler.url-1.10.2.jar
• io.wcm.handler.link-1.10.4.jar
• io.wcm.handler.media-1.16.0.jar
