Problem/Motivation

When trying to remove the last message in the thread this error appears:

TypeError: reset(): Argument #1 ($array) must be of type array, bool given in reset() (line 117 of modules/contrib/privatemsg/src/PrivateMsgService.php).

Steps to reproduce

- Install the Privatemsg module and enable it.
- Try to send a message to any user.
- Try to delete the message.

Proposed resolution

- The error appears because we removed all messages in the thread so we need to redirect the user to /messages when there are no messages in the thread
