Fix minor unicode OLX bug (Blockstore-based content libraries)

Feanil/fix contentstore views tests

Treat transcript content as unicode strings and convert them at any edge
where we encounter them.  One decision made here was to not update
edx-val it treats transcripts as byte but is much closer to the actual
files so it makes more sense over there. But within the platform they
are generally passed around as serialized json and so it's much better
for them to be unicode.

Python Requirements Update

BOM-866

Dictionaries are being rendered into the HTML but in different order between python2 and python3 and failing tests in python3.
The function parses and sorts the dictionary so that we get ordered data that can be compared in tests cases.

BOM-749: Explicity creating byte strings

python3 compatibility: regex needs bytes type strings to check bytes type response

python3 compatibility: etree returns a bytes type string so in py3 we need to decode it
to compare with a unicode string

Updated the division operation to make the output compatible with both python versions - BOM-874

BOM-840

Drop notes tables.
