Set GARBAGE_INTERVAL on 2.12 version

I tried with version 2.19, 2.18, and 2.17. Same error.

But, i did a workaround based on reply of @pabloFuente in this issue:

I set the variable with this config:

OPENVIDU_RECORDING_COMPOSED_URL=http://127.0.0.1

And on host OpenVidu server 2.19, i configured a Apache to serve the custom layout.

Now, recording with OpenVidu 2.19 is running fine.
