Issue 51169 - UI - attr uniqueness - selecting empty subtree crashes …

…cockpit

Description:  When processing the typeAheadChange we need to check for a empty
              string before treating the array like a list of objects.

              Also updated README with contribution instructions

relates: https://pagure.io/389-ds-base/issue/51169

Reviewed by: spichugi(Thanks!)

Improve handling of typeAhead values.

In some cases its an array of strings, and in some cases it's array of objects

+# Contributing
+-------------------------
 
+To test changes to the 389-console plugin, you can set up links from your workspace to a user's home directory
 
+- Create cockpit directory under user's home directory
 
+    mkdir ~/.local/share/cockpit/389-console
 
+- Link your workspace directory
 
+    ln -s /home/USERNAME/source/389-ds-base/src/cockpit/389-console/dist  ~/.local/share/cockpit/389-console
 
+- Then run the build & watch script.  This builds the UI and "watches" it for changes
 
+    cd /home/USERNAME/source/389-ds-base/src/cockpit/389-console/
+    ./buildAndRun.sh
 
+- All changes to the source code will be reflected in the UI without having to reinstall any packages.  You just need to reload the browser to see the changes.
