Deselected keywords should not be extracted again

[ruKurz]

When a user removes one of the extracted keywords from the list, the keywords come up again:

• when sending a new message
• when leaving the room and enter it again.

In both cases the state gets lost and therefore the time the user (human) has spend to tell the Smarti (machine) what he wants is wasted. Therefore the user is a kind of frustrated.

Deselected/removed Keywords should not pop up again when a new message is being sent or when switching between channels.

Additionally, deselected keywords shall be marked as removed for all providers, not only for one
