autofix: fix ReplaceTrailingDotsWithEllipsis to accept empty source strings

This should fix nijel/weblate#320

Having the ReplaceTrailingDotsWithEllipsis autofix enabled results in an _IndexError: string index out of range_ error whenever an empty source string is used (which is unlikely, but not technically impossible).

This patch solves this problem by first checking for non-emptiness of the source string.

For en_CA@foo it would first try en_CA and fallback to en.

This prevents various problems with non standard language names.

Fixes #318

This value is never used and causes problems with some
MySQL/Django/South version combinations.

The only reason this field originally had NULL attribute and it has it
now removed was migration path, where it was filled in by separate data
migration:

0018 - adds Change.translation field with NULL allowed and default
0019 - fills in Change.translation for all entries
0020 - removes NULL attribute

This fixes #319.

They use wildcard imports.
