ui-tag.c: do not segfault when id is missing from query-string
The purpose of the tag page is to print info about a specific tag, but if no tag was specified on the query-string cgit used to segfault. With this patch, cgit will fallback to the value of the 'h' parameter instead (which is never NULL due to prepare_repo_cmd() in cgit.c). It will now also verify that the specified tagname is in fact a valid ref in the 'refs/tags/' namespace, i.e. specifying 'id=master' will trigger a 'Bad tag reference' error.
