Purpose of this commit is to add some tests related to mine request. We add
tests checking IAP response management and lead creation. We introduce a
mock for IAP mine calls, as well as some tool data generation methods in
base IAP mock class available in iap_crm.
We also add some tests for corner cases (credit issue, no result, exception
during call) in order to improve coverage.
