Enable most LocalTargetDefinitionTests in verification builds

Don't disable LocalTargetDefinitionTests by default in verification
builds, only disable those that fail.
Some of the disabled tests should probably work even in verification
builds and IDE JUnit Plugin tests, but that is left for later.

And fix LocalTargetDefinitionTests.testDeleteCleansCaches() test-case
that is current failing in I-builds.
