Bug 21355: Prevent GetDailyQuote.t to fail when run after 23:00

Tests will fail (Jenkins run #554) if run after 23:00

 #   Failed test 'Id is correct'
 #   at t/db_dependent/Koha/GetDailyQuote.t line 72.
 #          got: 6
 #     expected: 8

 #   Failed test 'Timestamp 2018-09-15 00:44:46 is correct'
 #   at t/db_dependent/Koha/GetDailyQuote.t line 74.
 #          got: '2018-09-14 23:44:46'
 #     expected: '2018-09-15 00:44:46'
 # Looks like you failed 2 tests of 12.
 [23:44:46] t/db_dependent/Koha/GetDailyQuote.t
 Dubious, test returned 2 (wstat 512, 0x200)

Adding only 1 second will hugely reduce the risk of failure here.

It also updates a useless test (column 'quote' does not exist)
