Unserialization failure after upgrading to 3.7.0 (excludeIf related?)

[benjamintoussaint]

Q	A
Bug report?	yes
Feature request?	no
BC Break report?	yes
RFC?	no

Steps required to reproduce the problem

1. Upgrade from 3.6.0 to 3.7.0

Expected Result

• A working unserialization

Actual Result

• Error when unserializing:
  {"code":500,"message":"Notice: Undefined offset: 15"}

The excludeIf data appears to be missing from the $unserialized variable which apparently cause the $excludeIf property to be accidentally populated with the parentStr while that $parentStr data is missing at offset 15:

public function unserialize($str)
{
    $unserialized = unserialize($str);

    [
        $this->preSerializeMethods,
        $this->postSerializeMethods,
        $this->postDeserializeMethods,
        $this->xmlRootName,
        $this->xmlRootNamespace,
        $this->xmlNamespaces,
        $this->accessorOrder,
        $this->customOrder,
        $this->discriminatorDisabled,
        $this->discriminatorBaseClass,
        $this->discriminatorFieldName,
        $this->discriminatorValue,
        $this->discriminatorMap,
        $this->discriminatorGroups,
        $this->excludeIf,
        $parentStr,
    ] = $unserialized;
