Update test file with MD hashed password
Update test file with MD hashed password

With the feature of passwords getting automatically
upgraded to a hashed version, the default `admin`
password in the test-users file will get stored
as MD5 hashed during test execution. Commit this
change, so that the file isn't always showing up
as changed.
