using Python Shell i18n.twhas_key() causes an exception:
>>> import pwb, pywikibot as py
>>> from pywikibot import i18n
>>> ms = 'redirect-broken-redirect-template'
>>> b = i18n.twhas_key('de', ms)
Traceback (most recent call last):
File "<pyshell#5>", line 1, in <module>
b = i18n.twhas_key('de', ms)
File "pywikibot\i18n.py", line 500, in twhas_key
transdict = getattr(__import__("i18n", fromlist=[package]), package).msg
ImportError: No module named i18nThis is because the module is imported from "i18n" instead from "scripts.i18n".
We have to use messages_package_name instead of hardcoded "i18n" here.
