Fix crash on startup when building without environment variables

- Adds a check for the `CAST_APPLICATION_ID` variable in `CastCompat`.
  If it's null, casting will be disabled.
- Without a `PASTEBIN_DEV_KEY` sending logs would result in a generic
  "Failed to gather logs" message. This commit changes the message to
  something more accurate.
