Subject: chore: disable protocol handler dcheck

https://chromium-review.googlesource.com/c/chromium/src/+/6727594

The above CL introduces a new extensions API to register custom protocol
handlers. A DCHECK causes Electron to crash until we provide our own
registry. This patch disables the check until we support this.
