to close #270

I checked out pr-271 to produce embed_1.2.1.9000.tar.gz, Unfortunately I still see the problem:

══ Failed tests 
── Error ('test-umap.R:435:3'): keep_original_cols - can prep recipes with it missing ──

If you want to try, you can check out and install irlba 2.3.7 from https://github.com/bwlewis/irlba.git -- you should be able to reproduce the error.

Let me know how I can help if you need more testing. I don't quite understand the code right now but am happy to look in to this more if you need assistance.
