[Kotlin, Gradle] Fix legacy Android projects do not have associated test tasks for Android unit tests

The logic was relying on the 'KotlinTarget.presetName' value, which became always 'null' since the Kotlin 2.2.0 release.

Fortunately, we could rely on the 'KotlinTarget.platformType' value, which has a specific value for Android projects: "androidJvm". The new Android external plugin uses "jvm" for this property.
