A correction proposal should only be given if it is likely correct.
There can be many reasons why an import could fail: there might be
no read permission for the file, or the PYTHONPATH might be setup
incorrectly.

IOW, a hint about a missing __init__.py should only be given if
a directory with the name of module was found, but lacked an
__init__.py (i.e. in the cases where currently a warning is
produced).
