Description

If typeId==0 and full class name is written in the binary format, BinaryType.isEnum() method fails with the exception:

Caused by: org.apache.ignite.binary.BinaryObjectException: Failed to get binary type details [typeId=0]
  at org.apache.ignite.internal.binary.BinaryTypeProxy.target(BinaryTypeProxy.java:99) ~[ignite-core-1.6.7.jar:1.6.7]
  at org.apache.ignite.internal.binary.BinaryTypeProxy.isEnum(BinaryTypeProxy.java:86) ~[ignite-core-1.6.7.jar:1.6.7]

This happens because BinaryTypeProxy.target() method ignores this case. If typeId==0, It should look up full class name from the object and convert it to the actual type ID before trying to fetch metadata.
