Akim Demaille cf899f7a7c yacc: fix push parser ...

When a pstate is used for multiple successive parses, some state may
leak from one run into the following one.  That was introduced in
330552ea49 "yacc.c: push: don't clear
the parser state when accepting/rejecting".

* data/skeletons/yacc.c (yypush_parse): We reusing a pstate from a
previous run, do behave as if it were the first run.
* tests/push.at (Pstate reuse): Check this.
