[5.2.x] Fixed #29187 -- Fixed flaky receiver count assertion in signals
tests.
Signal.receivers prunes dead weak references lazily, so a weak receiver
garbage-collected elsewhere could still occupy a slot when
BaseSignalSetup.setUp() counted receivers. The test's own
connect/send/disconnect calls would then prune before tearDown()
counted again.
Backport of 15bcbeeb95ca34385c119acea14df1f5e7274d45 from main.
