VCR Tests Fail

[csogilvie]

It would seem that tests that use 'vcr' are failing.

I don't know enough about this to even begin to understand what it is failing on, but it makes it harder to find genuine test failures when these tests are always failing.

FAILED tests/pymonzo/test_accounts.py::TestAccountsResource::test_list_vcr - vcr.errors.CannotOverwriteExistingCassetteException: Can't overwrite existing cassette ('tests/pymonzo/cassettes/test_accounts/TestAccountsResource.test_list_vcr.yaml') in your current record mode ('none').

Yeah, sorry about that. Basically, I'm encrypting the VCR cassettes, because they contain real data from my account, but because of that there's no easy way to run these tests by someone else, including in the CI.

Mid term, I want to get rid of VCR usage because of how fragile it is.

I'll track the removal of VCR.py in #37
