Emit Enabled default configuration

[enumag]

This is not exactly a bug per se but it certainly caused a wtf moment for me.

So this morning I noticed that my projection was not running. When I checked it's status, I found this:

  "status": "Faulted (Enabled)",
  "stateReason": "'emit' is not allowed by the projection/configuration/mode",

Then I digged what the emit option is, which was easy to find here even with the error.

Then I checked how the projection was created. Prooph has a hard-coded &emit=1 here which got me confused.

The problem was that I'm using ProjectionsManager::updateQuery() when migrating to a new version. This method however has the $emitEnabled option which I did not notice and it defaults to false.

Maybe it's intended but it certainly caught me off-guard. When creating a projection there is no way to turn off the emit option, yet when updating it gets disabled by default.

Feel free to close this if this is intended. Just wanted to share my experience.
