Bug #3415 mysqlbinlog loses a USE command when LOAD DATA INFILE is involved

Description:
See how-to-repeat for a testcase

How to repeat:
Have db1 and db2.
Do
use db2;
INSERT INTO mytable3 VALUES(1);

Then in two simultanate threads, do
use db1;
LOAD DATA INFILE 'file' into mytable;
and
use db1;
INSERT INTO mytable2 VALUES(2);

Then in the output of mysqlbinlog you may have:

use db2;
INSERT INTO mytable3 VALUES(1);
# use db1;
# LOAD DATA INFILE 'file' into mytable; (that's the Create_file event)
INSERT INTO mytable2 VALUES(2);
LOAD DATA INFILE '/tmp/file' into mytable; (that's the Exec_load event)
and when you play this you will get "db2.mytable2" does not exist.
Because the "use db1" was commented, which is ok, but was forgotten for the INSERT.

Suggested fix:
Do not update 'last_db' if you are printing "use" with a #.
