bug(phases): mark remote HEAD and all ancestors as public

[vegerot]

steps to reproduce

1. sl clone a git repo with many commits and no branches named main or master (e.g. a repo with one branch named develop)
2. run sl sl

expected: should show one commit that is the public HEAD

actual:

$ sl sl
smartlog: too many (2699) commits, not rendering all of them
(consider running 'sl doctor' to hide unrelated commits)
@    652  Mar 31 at 12:27  Max.Coplan remote/develop
... shows every commit up until the initial commit

note: this bug is also visible in the commit message for c8b66c6

Explanation

c8b66c6 added support for cloning the remote git repo's HEAD (in this case develop), instead of main/master by default.

However, this doesn't mark remote/develop and its ancestors as public commits.

Suggested fix

When cloning a repository, mark the cloned head as public

I skimmed phases.py to see if anything stood out to me as a way to fix this bug, but didn't see anything. Would appreciate some direction on where to start looking

@vegerot thanks for reporting the issue. You can considering add the remote name in repo config

• This is the initial config:

  sapling/eden/scm/edenscm/git.py

  Line 88 in c8b66c6

  repo_config += "\n[paths]\ndefault = %s\n" % url

• This is how we read the config:

  sapling/eden/scm/edenscm/git.py

  Line 327 in c8b66c6

  def readconfig(repo):

You might need to add write logic for the repo config.

@zzl0 thanks for the ideas! What do you think of what I did in #607?
