Fix the rename that renamed itself

`sed s/_reconcile_tags/_lift_and_reconcile_tags/` ran over tags.py after the
new function was already written with the new name, so the definition became
`_lift_and_lift_and_reconcile_tags` while all 15 call sites were correct.
Twelve test modules failed to import.

The check that should have caught it is the reason it got through: the
verification grep piped output through `sed 's/:.*_lift/: _lift/'`, which
trims to the LAST `_lift` and therefore prints a doubled name identically to
a correct one. A filter that can only make wrong output look right is worse
than no filter.

Same sed also clobbered the docstring's historical reference — it read "it
used to be `_lift_and_reconcile_tags`", naming the function after itself.
