fix(tasks.extract_from_html): Catch UnicodeDecodeError

[grossir]

UnicodeDecodeError was bubbling because except clause was not catching it

Solves #181

[mlissner]

Seems fine. Do we need the DoctorUnicodeDecodeError anymore?

Thanks @grossir

[flooie]

@mlissner - sorry to get in the way of this.

[mlissner]

We passed like ships in the night! My thought was that if we want to remove it — you tell me — I could do it and then we'd know if my magic powers fix the deployment workflow.

[flooie]

I say let it disappear into the ether.

[mlissner]

Hm, there's something interesting (clever?) going on here:

doctor/doctor/lib/utils.py

Lines 93 to 95 in adf3912

	except UnicodeDecodeError as e:
	if not isinstance(s, Exception):
	raise DoctorUnicodeDecodeError(s, *e.args)

Hm...I don't have time to think through if we want to remove that or if it's doing something useful, but happy to do what you say.
