During tests, some creation of user records would unnecessarily trigger
password reset or set a password, both of which would trigger password
hashing which takes some time (for good reasons).
Fix by:
* passing no_reset_password in YAML tests and some Python tests still
missing it (a number of Python tests already used it)
* removing passwords from YAML records as they're never necessary, the
test user records are not expected to ever log in
