Bug 13226: 9999-12-31 should not considered as a valid date

DateTime::Format::DateParse (called in Koha::DateUtils::dt_from_string)
does not manage to parse 9999-12-31 if a time zone is given.

my $date = DateTime->new(year => 9999, month => 12, day => 31);
 => OK

DateTime::Format::DateParse->parse_datetime( '9999-12-31' );
 => OK

DateTime::Format::DateParse->parse_datetime( '9999-12-31',
 'America/Los_Angeles' );
 => KO (~20sec on my laptop)

It should not be considered as a valid date when the letter is parsed.

Note that to reproduce the problem you much be checking in items from an
account which has been restricted indefinitely (either manually or by
the overdues process). With this patch such checkins go from taking
around 50 seconds (in my test system) to around 7 to 10 seconds.

Good catch! Works as described, no problems found.
