Fix Bothub classifier and add tests

[matmsa27]

Hi @nicpottier , we fix it the ClassifierTypeBothub for bh and add BotHub type on the test list for run tests.

Thanks a lot.

Thanks, ya, that's kind of a shame, we are using a longer type for classifier types since that makes it easier for everyone. Why don't we change the type on the Bothub type to bothub on the RapidPro side. (I'm fine with that PR and this one in adding that) A quick DB shell can be used to update any classifiers already created but at least will keep things in sync.

Hmmm, yeah make sense. I opened a PR for RapidPro here. I will change classifier_type on mailroom_db.py to bothub, and I'll change slug on classifiers/types/bothub/type.py for bothub.

Here in this PR I'll remove the change for bh and keep bothub, and generate a new mailroom_test.dump.

Can I proceed with these observations?
Thanks a lot.
