When trying to create a simple cache with Cassandra store and have value
persistence strategy POJO, the following exception occurs

It looks like that recent changes of IGNITE-1903 are leading to this issue, as
we are starting to serialize cacheStoreFactory, which contains PojoFiled, which
in its turn has transient field accessor. This leads to accessor being null
after deserialization.
Works fine with Ignite 2.7.6.
Probably related to IGNITE-8500
