Merge duplicate UserProfileTest classes from ui-tests

So we have two classes, with the same names in distribution-tests/ui-tests. More exactly :

1.src/test/it/org/xwiki/test/ui/administration/UserProfileTest.java
2.src/test/it/org/xwiki/test/ui/UserProfileTest.java

Basically i have merged them, so the only remaining one is in

2.src/test/it/org/xwiki/test/ui/UserProfileTest.java
