stack: fix phasecache._phasesets check logic
When _phasesets is not None, it's a list, and it contains set()s of revisions
in a specific phase, starting from public, draft, secret and so on. But since
repos are supposed to have the majority of revisions in public phase, the first
element of this list is not a (potentially huge) set, but None.
Previously this code tried to check if there's any element that is None, and
was always finding None at index 0, so the short path was executed every time
and the rest of the function was never used.
Tests for the --stop flag for `hg evolve` command while resolving content-divergence
==================================================================================
The `--stop` flag stops the interrupted evolution and delete the state file so
user can do other things and comeback and do evolution later on
This is testing cases when `hg evolve` command is doing content-divergence resolution.
