Envelopes don't get removed from envelopes list

[StCyr]

Expected behavior

Envelope of deleted messages should automaticaly be removed from envelope list

Actual behavior

Envelopes don't get deleted. Refreshing the page several times doesn't even fix this.

Cliking on the envelope of a deleted message shows this:

Mail app

Mail app version: (see apps admin page, e.g. 0.5.3)

Mailserver or service: (e.g. Outlook, Yahoo, Gmail, Exchange,...)

Server configuration

Operating system: (e.g. Debian 8)

Web server: (e.g. Apache, Nginx,...)

Database: (e.g. MariaDB, SQLite or PostgreSQL)

PHP version: (e.g. 7.0)

Nextcloud Version: (see admin page, e.g. 13.0.2)

Client configuration

Browser: (e.g. Firefox 48)

Operating system: (e.g. Arch Linux)

Also related to #2064. I have yet to find out why this happens. Doesn't occur all the time for me. @rullzer noticed it as well.

As a start we should probably just delete the message from the cache. Right now we only change IMAP and hope that the next sync will update the cache accordingly.
