tests: simplify and document the sorting of pyflake messages
The pyflake messages are simply ordered by message type, path, line no (and
message text).
The message type is taken from the order of the filters.
The previous ordering looks complicated and illogically.
It was the following order (r'\3:\5:\4:\1:\2:' + line):
message (\3 and \5)
var name (\4)
path (\1)
line no (\2)
line reference
Ordering by var name before path looks illogically for me.
