[BUG] Send messages to chat option not working

[Larwck]

Describe the bug
'Send messages to chat' option being turned off does not prevent messages being sent to chat, however the messages that are sent are different than the format options in the fields shown.

Environment Details
Foundry VTT Version: 0.7.9
Mount Up! Version: 3.1.1

To Reproduce
Simply mount or unmount tokens while the 'Send messages to chat' option is unchecked.

Expected behavior
Nothing should be sent to chat.

Additional context
The format used in the messages is found in tokenAttacherHelper.js, where it can also be manually disabled by removing the 'ui['chat'].processMessage...' lines.
