phases: check secret presence the right way during discovery

There is an official function for this, lets use it.

This will prevent the code to break in the future while we refactor the phase

#!/usr/bin/env python3
# Dump revlogs as raw data stream
# $ find .hg/store/ -name "*.i" | xargs dumprevlog > repo.dump
