NormalizeBlogFolderName removed "_1".."_9" as unanchored substrings, so a
folder suffixed past a single digit lost the wrong characters: "_10" hit
the "_1" rule and left the trailing "0" welded to the name, importing
zomb-eh_10 as blog "zomb-eh0". That name does not exist on Tumblr, so
every post imported under it 404s on --collect forever.
Anchor the strip to a trailing _<digits> instead. This also fixes blogs
whose real name contains "_1" (some_1blog no longer becomes someblog) and
folders suffixed "_0", which were not stripped at all.
Verified against the live folder tree: zomb-eh_10 is the only existing
folder whose normalized name changes.
