context: cache self._status correctly at workingctx.status

Before this patch, "workingctx.status" always replaces "self._status"
by the recent result, even though:

  - status isn't calculated against the parent of the working directory, or

  - specified "match" isn't "always" one
    (status is only visible partially)

If "workingctx" object is shared between some procedures indirectly
referring "ctx._status", this incorrect caching may cause unexpected
result: for example, "ctx._status" is used via "manifest()", "files()"
and so on.

To cache "self._status" correctly at "workingctx.status", this patch
overwrites "self._status" in "workingctx._buildstatus" only when:

  - status is calculated against the parent of the working directory, and
  - specified "match" is "always" one

This patch can be applied (and effective) only on default branch,
because procedure around "basectx.status" is much different between
stable and default: for example, overwriting "self._status" itself is
executed not in "workingctx._buildstatus" but in
"workingctx._poststatus", on stable branch.
