Problem:
If an existing swauth deployment changes `auth_type` in conf file to a
different one (for example: sha1 to sha512), all attempts to authorize
existing/old users will fail because of change in encoder type.
Fix:
With this change, the credentials match is done using an encoder with
which the password was initially encoded. This allows swauth deployments
to change auth_type and old users will still be able to authorize.
