All you have to do is install a factory image of 5.0.1 to the Nexus before you update fully.

Wait. I've had positive and reliable experiences running Android 5.0.1 on Nexus 10, Nexus 7, and Nexus 5. However, my Nexus 4 experiences reboots with Android L and a friend's Nexus 4 outright powers down regularly. That said, a bugfix Android 5.0.2 is rolling out to Nexus devices right now. So wait.
You can either upgrade to L via TWRP itself (some reported having trouble with TWRP 2.8 and suggested trying 2.7) or revert from TWRP back to stock recovery if you want to go the OTA way (I guess that's what you're trying to do, you're not clear on that in your question). Also instead of TWRP you can try ClockworkMod recovery. edit: typo
I use the Nexus Root Toolkit for Windows by wugfresh, it will allow you to unroot and revert to stock with a button click. It also includes full instructions on any setup you need to do prior. You can find it here: http://www.wugfresh.com/nrt/. It will also allow you to choose TWRP or ClockworkMod if you wish and can help you install new ROMs too.
You can't get OTA updates while the phone is rooted. What you need to do is un-root the phone, install the OTA update, then re-root the phone once you're done. Also, OTA updates are best done using the stock recovery.
It could be that the new update needed an extra permission. If that is the case, your app won't update automatically. It needs yo to accept the new permissions first.
