Update tests on decompiled text for JS

Because .kjsm files now contain all declarations from the package (contrary to
the JVM decompiler which produces one file for one class/package facade), some
common decompiled text tests started to behave differently on JVM and JS.
Update two of them (Modifiers, ClassWithClassObject) to make results the same,
copy another (TypeAliases) to JVM-/JS-specific tests with different outputs
