[MU] Emptying trash: Many unnecessary Email/query + Email/get requests

[chibenwa]

Description

WHEN I empty my trash with 180 messages in it

THEN Tmail...

• Performs an initial email/query + email/get operation to catch the emails
• Then Email/set destroy a batch of mails
• Then resyncs too much on websocket notifications (not the issue here)
• Then issue hundreds of Email/query + Email/get that actually returns empty payload <= that 's the issue here.

Why are those requests made?

Expected result

Avoid needless requests when emptying trash...

(is it possible that resynch on an empty mailbox triggers an aggressive Email/query+get ) ?

If so having a debounce on this behaviour would be nice!

• Replace Email/query + Email/get + Email/set with Email/query + Email/set

Replace Email/query + Email/get + Email/set with Email/query + Email/set

+1 but notDestroyed setError results will need fine tuning...

If not found treat the message as deleted, otherwize do considère deletion failed.

(this multiple entry issue is temporary and will disapear with multiple composer so is temporary.
A cache that handles not gracefully multiple entries is better than no cache at all...
Si please do not over engineer the multiple cache entry issue...)
