This ended up being just a simple Python3 issue, and the solution below
works fine, as far as I can tell so far. I post it here in case anyone
finds it useful:
I defined a "modules checkpoint" to which I can roll back to:
>>> from modules_checkpoint import ModulesCheckpoint
>>> checkpoint = ModulesCheckpoint()
>>> from gramps.webapp.databases.database1 import database
>>> database.dji.Person.all().count()
4
>>> checkpoint.reset()
>>> from gramps.webapp.databases.database2 import database
>>> database.dji.Person.all().count()
0
>>> checkpoint.reset()
>>> from gramps.webapp.databases.database1 import database
>>> database.dji.Person.all().count()
4
(showing the different counts in two different Django databases, defined in
different settings.py). Code is below.

# modules_checkpoint.py
import sys
class ModulesCheckpoint(object):
def __init__(self):
self.original = sys.modules.copy()
def reset(self):
# clear modules:
for key in list(sys.modules.keys()):
del(sys.modules[key])
# load previous:
for key in self.original:
sys.modules[key] = self.original[key]
