Bug: Transistion from PersistentVector to SmallPersistentVector on removing an element fails

[mschirmacher]

Tested with '0.3.2'

    @Test
    fun foo() {
        Array(33) { "" }
            .asList()
            .toPersistentList()
            .removeAt(32)
    }

Results in:

Assertion failed
java.lang.AssertionError: Assertion failed
	at kotlinx.collections.immutable.internal.CommonFunctionsKt.assert(commonFunctions.kt:8)
	at kotlinx.collections.immutable.implementations.immutableList.SmallPersistentVector.<init>(SmallPersistentVector.kt:18)
