[PATCH/RFC 2/2] Remove $tagobjid from tagcontents population

[Dave Dulson <dave@dulson.com>]

When the showtag proc is called directly after the tag has been
created rereadrefs hasn't been called, meaning the tag doesn't exist
in $tagobjid. This causes the cat-file to fail.
Instead of using $tagobjid, pass the $tag directly, ensuring the tag
contents are populated correctly.
