core/source: use import error (#211)

core/source: use import error

uses the more broad ImportError
instead of ModuleNotFoundError

reasoning being if some submodule
(the one I'm configuring currently is
my.twitter.twint) doesn't have additional
imports from another parser/DAL, but it
still has a config block, the user would
have to create a stub-config block in their
config to use the all.py file

my/core/__main__.py
