This PR removes @ClassPathExclusions in SpringBootPluginTests as it doesn't seem to be necessary.

Thanks, @izeye. Unfortunately, it is necessary. kotlin-daemon-client embeds an old version of net.rubygrapefruit.platform which is incompatible with the version that Gradle's generated API embeds. It isn't a problem in a TestKit-powered integration test where, I think, Gradle's class loader isolation keeps the two separate but is a problem in tests that use ProjectBuilder when kotlin-daemon-client appears on the classpath before Gradle's generated API jar.
