Broadcast module - Filters not working

[Naroh091]

Describe the bug
Messages are never sent to users matching the filters.

To Reproduce
Steps to reproduce the behavior:

1. Enable the broadcast module.
2. Open a conversation using the emulator.
3. Go to the broadcast module, create a new one, and add channel == 'web' as a filter. Remember to click the 'Add' button to actually add the filter.

Expected behavior
The message is sent to the matching users, which are those with channel == web, so at least the emulator conversation should receive it.

Instead, no message is sent.

Environment (please complete the following information):

• Botpress Version: 12.30.8

Additional context
The main problem is that in daemon.ts, line 38, Botpress returns this typeof v !== 'undefined' && v !== null instead of the value of v, the variable in which the result of the matching is stored. If everything works fine v won't be undefined nor null, thus returning "true", which is the final value of drop of the dropPromise, dropping that message.

From what I've read I know that the Broadcast module was never ready, but I think it would be nice to have at least this fixed - I'll send a pull request in a couple of minutes.
