Bug #34750 Print database name in Unknown Table error message

Description:
A familiar error:

ERROR 1051 (42S02) at line 8: Unknown table 'comment'

It would be very helpful if it included the DB name.

How to repeat:
mysql> drop table test.table_that_does_not_exist;
ERROR 1051 (42S02): Unknown table 'table_that_does_not_exist'

Suggested fix:
This would be great:

mysql> drop table test.table_that_does_not_exist;
ERROR 1051 (42S02): Unknown table 'test.table_that_does_not_exist'

Thank you for a reasonable feature request.

As I understand it, we want to print the database name if the current database is different from where the non-existing table is attempted deleted. Thus,

  use t;
  drop table test.notable;

should warn: "ERROR 42S02: Unknown table 'test.notable'", whereas 

  use t;
  drop table t.notable;

should warn: "ERROR 42S02: Unknown table 'notable'".
