Unwanted comma typo results in code being tuple not str

[code-review-doctor]

Unwanted comma on line 609 results in code being set to a tuple rather than a string.

django-cities/cities/management/commands/cities.py

Lines 608 to 609 in c811bbb

	if hasattr(District, 'code'):
	defaults['code'] = item['admin3Code'],

A comma makes it a tuple (no need for parent, all it takes is one comma).

Solution is to remove the comma from the end of the line. I can do that for you if you want?
