On python 2.7.10, filtered log messages raise `TypeError: not enough arguments for format string`

[grzes]

'appending parent:\n%s\ncontent:\n%s' % (parent, content), works, but:
'appending parent:\n%s\ncontent:\n%s' % list((parent, content)) fails with a TypeError.

Some of googleads built in LogFilters (_SudsMXCoreFilter and _SudsMXLiteralFilter) convert the log record.args from tuple to list resulting in errors.

Hello,

Thanks for the report and PR! I've been able to reproduce this issue. Due to how our development cycle works, I intend to have this merged and integrated on our side by the next Google Ads release.

Regards,
Mark
