Feature: Add handling of BadResponseException

[glensc]

Not sure what the handling should be. So added it to retry list.

WARNING  Bad Response - Response could not be parsed for plextraktsync.trakt_api.collected(), retrying after 1
         seconds (try: 1/5)
WARNING  Bad Response - Response could not be parsed for plextraktsync.trakt_api.lookup(), retrying after 1 seconds
         (try: 1/5)
WARNING  Bad Response - Response could not be parsed for plextraktsync.trakt_api.lookup(), retrying after 2 seconds
         (try: 2/5)
WARNING  Bad Response - Response could not be parsed for plextraktsync.trakt_api.lookup(), retrying after 3 seconds
         (try: 3/5)
