MXS-2111: Use authentication_string when password is empty

Browse Source 
If the password field in mysql.user is empty, it is possible that the
actual password is stored in the authentication_string field. Most of the
time this happens due to MDEV-16774 which causes the password to be stored
in the authentication_string field.

Also added a test case that verifies the problem and that it is fixed by
this commit.
