fix(plugin): upgrade to latest version of Sentry and uWSGI

[AlbericTrancart]

Hey @unbit!

I am not proficient in C but this should fix https://github.com/unbit/uwsgi-sentry/issues/2.

What didn't work:

• Sentry DSN parsing with optional secret key
• removing the dashes in the event uuid (maybe the uwsgi_uuid function changed in the meantime?)

I tested it successfully with the latest version of Sentry and uWSGI.

Maybe fork the repo and publish your version on pypi 🤔
