Midas API throws 500 when trying to authenticate without a Default API key

[mgrauer]

@sankhesh found this when trying to use Pydas. He logged into a midas system, and had an API key with a name that wasn't Default, but no Default API key. He got a 500 with this stack trace:

Caught PydasException: 'Request failed with HTTP error code 500'
Waiting 5 seconds, then retrying request
Caught PydasException: u'Request failed with Midas error code -150: Unable to authenticate. Please check credentials.'

and in the Midas logs

When I said

He logged into a midas system

I meant he attempted to call pydas.login().

Should have been more clear.

That line number corresponds to the midas.user.apikey.default (RPC) or /system/defaultapikey (REST) API calls, which are never called by any other method on the server. Therefore, this is either a bug or feature related to Pydas with respect to the following line: https://github.com/midasplatform/pydas/blob/master/pydas/api.py#L70
