add travis for repo updates in leadconduit channel

This line change doesn't have anything to do with the addition of the slack notifications. 

On one hand, it's probably perfectly valid to leave this way. Nothing should break. On the other hand, it's best to minimize "collateral damage" when making changes. That way, no one will ever think that the ancillary changes are actually a necessary requirement for the primary change you're making. 

Given that, do you mind reverting the change to this line?
