Summary: D13853115 adds `edenscm/` to `sys.path` and code still uses `import mercurial`. That has nasty problems if both `import mercurial` and `import edenscm.mercurial` are used, because Python would think `mercurial.foo` and `edenscm.mercurial.foo` are different modules so code like `try: ... except mercurial.error.Foo: ...`, or `isinstance(x, mercurial.foo.Bar)` would fail to handle the `edenscm.mercurial` version. There are also some module-level states (ex. `extensions._extensions`) that would cause trouble if they have multiple versions in a single process. Change imports to use the `edenscm` so ideally the `mercurial` is no longer imported at all. Add checks in extensions.py to catch unexpected extensions importing modules from the old (wrong) locations when running tests.
