Fix Gradle 'konan' plugin tests

The konan plugin checks the GRADLE_METADATA
feature preview option and enables publication
only if this option is specified. But since version
6.0 Gradle metadata is enabled by default and the
corresponding feature preview option was removed
causing failures of konan plugin tests.

This patch removes the checks mentioned above to
fix these tests.
