[PATCH v3 2/2] stash: invoke rerere in case of conflict

[Phil Hord <hordp@cisco.com>]

'stash apply' directly calls a backend merge function
which does not automatically invoke rerere.  This
confuses mergetool when leftover rerere state is left
behind from previous merges.

Invoke rerere explicitly when we encounter a conflict
during stash apply

Change the test for this flaw to expect success.
