Fix crash after pressing F1.

Moved ImGui::Render(); to the main rendering loop for now so it'll always run and not accidentally abort when uiEnabled is false.

Issue:

scuffed_mc: /home/david/ScuffedMinecraft/ScuffedMinecraft/vendor/imgui/imgui.cpp:10090: void ImGui::ErrorCheckNewFrameSanityChecks(): Assertion `(g.FrameCount == 0 || g.FrameCountEnded == g.FrameCount) && "Forgot to call Render() or EndFrame() at the end of the previous frame?"' failed.

Thread 1 "scuffed_mc" received signal SIGABRT, Aborted.
