Subject: [PATCH] Fix R2dbcTransactionManager debug log: don't log a Mono
 (#29800)

When logging the current connection inside R2dbcTransactionManager
doBegin, the mono object was logged instead of the connection lambda
parameter.

Other similar debug-level logs do use the actual Connection object,
so this commit does the same.
