Revert "input: De-duplicate titles"
This reverts commit 66401825. This triggers a race between the interface and the input thread. The playlist signals that a new input_thread_t is now the current item, while the input thread tries to create the input_source_t containing the titles. If the interface reacts to the new item and tries to refresh the titles before the input_source_t has been assigned to input_thread_private_t::master, a crash will occur. IMHO, having the titles duplicated is best for now, considering that there will be massive changes to the playlist in 4.0
