inconsistency in reporting from mdbox_deleted

[Marc]

This reports all folders, ok

[@ testtest]# doveadm -o mail_location=mdbox_deleted:/home/mail-archive/testtest/Archive:INDEX=/home/archiveindex/testtest/index mailbox status -u testtest 'messages vsize' '*'
2011 messages=0 vsize=0
2012 messages=0 vsize=0
2013 messages=0 vsize=0
2014 messages=0 vsize=0
2015 messages=0 vsize=0
2016 messages=0 vsize=0
2017 messages=0 vsize=0
2018 messages=0 vsize=0
2019 messages=0 vsize=0
doveadm(testtest): Error: Mailbox Archive: Failed to lookup mailbox status: Mailbox doesn't exist: Archive
INBOX messages=15 vsize=12066832


This gets folder INBOX, ok 

[@ testtest]# doveadm -o mail_location=mdbox_deleted:/home/mail-archive/testtest/Archive:INDEX=/home/archiveindex/testtest/index mailbox status -u testtest 'messages vsize' 'INBOX'
INBOX messages=15 vsize=12066832


This reports error that a folder does not exist, ok

[@ testtest]# doveadm -o mail_location=mdbox_deleted:/home/mail-archive/testtest/Archive:INDEX=/home/archiveindex/testtest/index mailbox status -u testtest 'messages vsize' 'asdfasdfasdfasdf'
doveadm(testtest): Error: Mailbox asdfasdfasdfasdf: Failed to lookup mailbox status: Mailbox doesn't exist: asdfasdfasdfasdf


This query for Archive/2012 reports same as for 2012(?), by design, I guess ok

[@ testtest]# doveadm -o mail_location=mdbox_deleted:/home/mail-archive/testtest/Archive:INDEX=/home/archiveindex/testtest/index mailbox status -u testtest 'messages vsize' 'Archive/2012'
Archive/2012 messages=0 vsize=0


This reports 0?, This should either report the folder does not exist, or it should report the same as getting the INBOX, like previous result

[@ testtest]# doveadm -o mail_location=mdbox_deleted:/home/mail-archive/testtest/Archive:INDEX=/home/archiveindex/testtest/index mailbox status -u testtest 'messages vsize' 'Archive/INBOX'
Archive/INBOX messages=0 vsize=0
