 [2.2.x] Fixed #30325 -- Reverted "Fixed #29725 -- Removed unnecessary join
 in QuerySet.count() and exists() on a many-to-many relation."

 This reverts commit 1299421cadc4fcf63585f2f88337078e43e660e0 due to
 a regression with custom managers.

 Backport of 5f7991c42cff73b6278106d499d719b726f85ead from master
