When sync-diff verifies data, an error is reported if the upstream and downstream tables are inconsistent

[jt20190617]

Bug Report

Please answer these questions before submitting your issue. Thanks!

1. What did you do?
   upstream: tidb, and have 2 tables: t1,t2
   downstream: tidb, and have 1 tables: t2

Then check the data with sync-diff: ./sync_diff_inspector --config=config.toml

2. What did you expect to see?
   Sync-diff notices that there is an additional T1 table upstream, records this information, and proceeds to check the other tables

3. What did you see instead?
   Sync-diff logs out with an error.

4. What version of TiDB are you using (tidb-server -V or run select tidb_version(); on TiDB)?
   all version

5. which tool are you using?
   sync-diff

6. what versionof tool are you using (pump -V or tidb-lightning -V or syncer -V)?
   all version

The workaround is set the correct table name with table filter.
