When a user create a page with the title "contact" the path will be contact. This happens because os_pages took over pathauto functionality. @ran81 fix that only for pages node types since only on pages node that occur.

For you concern:
When a user want to set another path  he will need to un-check the automatic path and set one of his and the normal flow will ocure(system path can't be set etc. etc.) The fix on this PR will not affect the other node types flow for path generations so i can't see where is the problem
