Do not translate debug messages

LOG.debug messages do not need to be translated. The rdb driver
has a couple of debug messages that are translated. This patch
removes those debug translations.

Also, logging exception.ImageUnacceptable can contain non-ascii
characters. This patch fixes this by using six.text_type to
properly translate the exception.
