Django Signals integration breaks on partial objects for python <3.10

How do you use Sentry?

Self-hosted/on-premise

Version

1.9.9

Steps to Reproduce

1. Use python older than 3.10.
2. Register a partial function as a signal handler.

Expected Result

Signal is traced correctly.

Actual Result

Exception is raised from _get_receiver_name function as partial objects don’t have __module__ before python 3.10 (and even there it’s undocumented from what I can see).

It fails in our tests where we don’t even register any signals so either Django itself or some kind of integration (Sentry?) registers such signals by default.

The whole signals integration is missing a capture_internal_exceptions context too I believe.

Thanks for the update. I could now reproduce the error and have created a fix.

Finally, all the tests pass @sl0thentr0py could you please re-review? (The name generation function is now kind of complicated, but it generates nice names for python 2 and up and also for partials and normal functions)
