[java] KUDU-3349 Fix the failure to demote a leader
KuduScanToken gets a wrong tserver's uuid whose format is something
like: '<ByteString@6dffd497 size=32
contents="fc07f681d3ea4bab9bc5ec8090ab9437">',
the expected uuid should be "fc07f681d3ea4bab9bc5ec8090ab9437".
This issue caused RemoteTablet to fail to demote a leader, and the java
client always sends write ops to the demoted leader. As a result, there
are a lot of "PendingErrors overflowed. Failed to write at least 1000 rows to
Kudu".
After this fix, the write ops, especially the deleting, will be faster.
