As the db_connect_id gets set up by mysql_init(), the db_connect_id will be an
object with empty settings instead of just empty. Even if mysql_real_connect()
encounters an error upon connecting, the db_connect_id is still set. This
will result in trying to just access the database which obviously does
nothing.
By setting db_connect_id to an empty string, the script will not try to query
th database and properly handle any errors that occur upon connecting.

[ticket/12704] Improve the load time information in the footer when enabled
PR #2570 has added new constant to display load time information without
debug mode is being on (https://tracker.phpbb.com/browse/PHPBB3-12687).
This patch expands the total load time info with SQL/PHP load times,
while hiding the additional info with <abbr> element.
