Comment 1 for bug 1301353

The fix from Jesse was not actually related to *this* bug. This bug is the fact that if you are on Trusty and have "juju-mongodb" installed (say via juju-local), the test suite still fails because it is looking for "mongod" to be in $PATH.
We shouldn't have to add a symlink for the test suite to run (or install mongodb-server). Instead, it should use /usr/lib/juju/bin/mongod if it cannot find mongod in $PATH.

I still want to prefer mongod in $PATH because the charm store tests need the v8 engine that is not available in juju-mongodb.
