When we added more realistic hours of operation for some of the branches,
several of the live_t regression tests failed because they depended on the
default hours of operation for BR4. Rather than change the regression test,
just switch BR4 back to the default hours of operation and use BR1 as the
closed-on-weekends branch instead.
