DyRepos.add() does not include a message when throwing IllegalArgumentException

[carlosmiranda]

At the moment, DyRepos.add() will throw an IllegalArgumentException when it finds that the supplied repo already exists. However, it does not include any message in the exception that it throws, which does not help in finding out what went wrong.

We should add an exception message that specifically states what happened, something similar to:

Repo [repo name] already exists
