Bug 16636: t/00-load.t warning from C4/External/BakerTaylor.pm

Bug 16636: t/00-load.t warning from C4/External/BakerTaylor.pm

Since the tests are expecting an initialize function, the
initialize call was just moved outside of the INIT block.

TEST PLAN
---------
1) prove t/00-load.t
   -- warnings about INIT for BakerTaylor
2) prove `git grep -l BakerTaylor | grep [.]t$`
   -- should all run okay
3) apply patch
4) repeat steps 1 and 2
   -- warning should be gone, and everything else run okay
5) run koha qa test tools
