test_stopServiceNoReconnect fails with twisted >= 26

[sanvila]

Hello. As reported to Debian:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1137658

when building this project on a recent Debian unstable system, the build fails due to failing tests:

ERROR: test_stopServiceNoReconnect
(test_component.ComponentTest.test_stopServiceNoReconnect)
When the service is stopped, no reconnect is attempted.

This is most probably because of the new twisted, now at version 26.4.0.

I managed to fix the test failure by applying this patch:

https://salsa.debian.org/python-team/packages/wokkel/-/raw/master/debian/patches/fix-test-for-twisted-26.patch?ref_type=heads

but of course we would prefer the "official" fix, if any.

Thanks,
