mq: examine "pushable" of already applied patch correctly

Before this patch, "hg qselect" with --pop/--reapply may pop patches
unexpectedly, even when all of patches applied before "qselect" are
still pushable.

Strictly speaking about the condition of this issue:

  - before "qselect"
    - there are N applied patches
    - the index of the guarded patch X in the series is less than N

  - after "qselect"
    - X is still guarded, and
    - all of applied patched are still pushable

In the case above, "hg qselect" should keep current status, but it
actually tries to pop patches because of X.

The index in "the series" should be used to examine "pushable" of a
patch by "mq.pushablek()", but the index in "applied patches" is used,
and this may cause unexpected examination of guarded patch.

To examine "pushable" of already applied patch correctly, this patch
uses "mq.applied[i].name": "pushable" is the function introduced by
the previous patch, and it returns "mq.pushable(mq.applied[i].name)[0]".
