Test snippet format matches a directory it is in

[EgZvor]

(see commit cfc7e52)
An UltiSnips snippet was added into "snippets" directory which should
contain snipmate snippets only. This led to a parsing bug in UltiSnips.

An error occured. This is either a bug in UltiSnips or a bug in a
snippet definition. If you think this is a bug, please report it to
https://github.com/SirVer/ultisnips/issues/new

Hi @EgZvor!

The python problem has been fixed now, but I like your addition to the tests. Could you remove the changes to the python snippets and keep just the new test please?

Thanks :)

Hello, @lpil.

The python problem has been fixed now

That is good to know.

I've removed the unnecessary code.
