Revert "UI: Add checks for overwrite setting to replay buffer"

This reverts commit 02f3495b72.

Multiple issues have come up with this commit. One issue is that
suddenly replays are overwriting themselves despite the option being
disabled. Second issue is that slashes to separate files into
subdirectories no longer work properly with replay buffers.

I'm just reverting it. I do not care enough about this feature to try to
fix it or wait on a fix. If someone wants to fix it they can create a
new PR for it.
