Georgi Kodinov e953a26df5 Bug #38701: Crash in String::append when inserting duplicate empty strings an uft8 ...

SET col
                  
When reporting a duplicate key error the server was making incorrect assumptions 
on what the state of the value string to include in the error is.

Fixed by accessing the data in this string in a "safe" way (without relying on it
having a terminating 0).
      
Detected by code analysis and fixed a similar problem in reporting the foreign key
duplicate errors.
