Hi team,

While migrating users from a foreign system into the Member table, a bug surfaced in the way password hashes are handled.

It seems Security::encrypt_password() doesn't differentiate between:

1. plaintext passwords needing hashing for the first time (`Salt` is NULL)
2. hashed but unsalted passwords (`Salt` is empty string '')

This can be fixed in:

by changing:
$salt = ($salt) ? $salt : $e->salt($password);

$salt = isset ($salt) ? $salt : $e->salt($password);

Cheers, Matt
