When IC is on and new Kotlin class is referencing
new Java class, new Kotlin file is compiled twice,
because JPS thinks new Kotlin class is affected by
new Java class (see https://youtrack.jetbrains.com/issue/KT-20318).
This does not happen when IC is off, and KotlinBuilder
requests chunk rebuild (see previous commit).
I decided to remove the reference, because the issue
is now known, and the reference is non critical for the test.
