The
`IncrementalJsFirKlibCompilerWithScopeExpansionRunnerTestGenerate
.testSerializedSubClassAndChangedInterfaces`
test fail because the checksums of
the `manifest` files don't match
after the full recompilation.
It happens, because the `b.kt` file may be passed
to the compiler before `a.kt`, in which case while
generating the data class members the compiler
will generate a call to `Any::hashCode` when
accessing the hashcode of the `a` property instead
of generating a call to the fake override
`A::hashCode`.
When working with PSI, the compiler sorts the
input files to at `KotlinCoreEnvironment.kt:200`.
This change removes the flaky
behavior by sorting the input files.
