Because of the relay before lmtp issue we now add and remove QEntrys
based on their message-id. But if the cleanup line containing the
message-id appears twice in the log for the same QEntry it keeps a weak
reference to itself which leads to a panic because of a mutable borrow
while it is already mutably borrowed in the 'finalize' function.
To circumvent this we check after the lookup if it is the same QEntry
and if so, insert it again with that message-id in the lookup table and
don't add the weak reference.
