Login broken in Python3

When attempting to login with REST API:

[2021-04-07 11:05:35,396] ERROR in app: Exception on /api/v0.1/login [POST]

    'token': token.decode('UTF-8')
AttributeError: 'str' object has no attribute 'decode'

This is due to Python3's unicode-default strings.

Suggested fix: Remove the .decode() call or try

token': token if type(token) is str else token.decode('UTF-8')

if Python2 compatiblity is required

looks like its related to PyJWT https://stackoverflow.com/a/65484529

according to the changelog, in v2.0.0+

Return tokens as string not bytes (#513) by @jpadilla

[DustinKLo]

we'll version lock it to PyJWT==1.7.1 for now and can properly address it later
