[pywikibot] Pywikibot-test OAuth and Travis settings

Hi everyone! Nearly two weeks ago some of our travis build jobs related to testing OAuth have started to timeout.[1] I think it is related to travis misconfigured enviroment variables. Perhaps someohne has changed them? Unfortunately I don't have access there and I don't know who has. If you're the one, please take a look at T173498[1], we probably need to check/reset OAuth token values. Therefore other than having access to travis settings, knowing the authentication information for Pywikibot-test account is required.[2] Thanks!
