Minor Bug in bkT dyncov LL

[pschil]

While introducing tests against the dyncov LL in #110 it was found that not all tests as described in #98 hold.

bkT=T*C is not true for gamma=0:
Instead of 38 (Tcal) it yields 37.85714. This likely is because something slipped by a day (ie 0.15 is 1/7 of a weekly period).

The final LL values are still equal to the nocov LL values and therefore the test was commented out and the LL left as is.
