Bug: If document's title tag is empty, title extractor sets the snapshot title to "</title"

[rmohns]

Describe the bug

I saved a webpage which is terribly coded by hand, and has an empty title tag. (Literally: `

'.) The resulting snapshot is named "</title". Easy to change but odd.

TBH I'm not sure if you should care, since we may not care if horribly invalid documents create errors. But on the off chance that it's easy to check for and change this in the code, am filing bug report. (Perhaps such snapshots could be named "No document title found".)

Steps to reproduce

1. Saved this page to ArchiveBox: http://wildwestcycle.com/f_oiltempdegradation.html
2. Snapshot title is </title

[pirate]

Yeah should be, try the latest dev build https://github.com/ArchiveBox/ArchiveBox#install-and-run-a-specific-github-branch or v0.7.2

comment back if it's still happening and I'll re-open it
