test coverage numbers are out of whack when the config file points to multiple accomplishments directories

[Matt Fischer]

When you run the battery and your config file points to more than one accomplishments directory, you get a coverage number of 50% (and 2 Scripts). Only 1 script is ever run, presumably the first one in the path, and the coverage should be 100%

Config File:
[config]
...
accompath = /home/mfisch/experiments/accomps/ubuntu-community-accomplishments/master:/usr/share/accomplishments

Output:
mfisch@caprica:~/experiments/accomps/ubuntu-community-accomplishments/master/tests/ubuntu-community$ accomplishments-battery -s ubuntu-community/attend-uds
