Summary0013924: Problem with preferences having empty value -> Can'T login
DescriptionFollowing situation:

A module ship a row for ad_preferences for setting a startpage with some non-empty value and without any filter on user or role etc...

Now i wanted to create a more specific preference for a specified user 'classic' with an empty value which should have higher priority.

After doing this change i could not change role or login anymore because of some NPE happening.

Error as logged during login process:
930160 [http-8080-6] ERROR org.openbravo.erpCommon.security.Menu - HTTPSecureAppServlet.service() - exception caught:
java.lang.NullPointerException
    at org.openbravo.erpCommon.businessUtility.Preferences.isHigherPriority(Preferences.java:444)
    at org.openbravo.erpCommon.businessUtility.Preferences.getAllPreferences(Preferences.java:74)
    at org.openbravo.base.secureApp.LoginUtils.fillSessionArguments(LoginUtils.java:201)
    at org.openbravo.base.secureApp.HttpSecureAppServlet.service(HttpSecureAppServlet.java:311)
    at javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
Steps To Reproducei.e. Install new layout modules (navigationbar)
Create a new user called 'classic' assign it i.e. System Administrator role
Create a new preference for entry startpage with no value
which is restricted to Username: 'classic'
Logout
Try to login -> does not work, NPE in the log

Tested working fine now, no NPE anymore and the correct, more strict preference is used.
