localrepo: pass hook argument TXNID to pretxnopen hooks

Before this patch, hook argument `TXNID` isn't passed to `pretxnopen`
hooks, even though `hooks` section of `hg help config` describes so.

  ``pretxnopen``
    Run before any new repository transaction is open. The reason for the
    transaction will be in ``$HG_TXNNAME`` and a unique identifier for the
    transaction will be in ``HG_TXNID``. A non-zero status will prevent the
    transaction from being opened.
