get_unbound_discharge returns a tuple with (value, error)

Bug #1594636 reported by Leo Arias on 2016-06-21

Bug Description

In snapcraft/storeapi/, the method get_unbound_discharge returns a tuple. The first element is the return value on success, the second is the error on failure.

That's not pythonic. The method should return the value or raise an exception.


 * For users, none.

 * For developers, the code is less clear because it's not following the common python practices.

[Test Case]

 * Run all the methods that access the store:
   login, upload, download.

[Regression Potential]

 * This could affect the commands that access the store.

Also get_macaroon in the same file returns a tuple.
