This method attempts to rebuild the IssueRef that the user chose the
last time that they scraped this comic. If it can do so, it will
return that IssueRef. If not, it will return None, or the
string "skip" (see below).
If the user has manually added the magic CVDBSKIP flag to the tags or
notes for this book, then this method will return the string "skip",
which should be interpreted as "never scrape this book".
