### Summary Removing deploy keys doesn't actually remove them if they've been linked to another project. ### Steps to reproduce 1. I created "project_a" and "project_b" 1. I added "newkey" to the deploy keys of "project_a" 1. I _enabled_ the "newkey" on "project_b" since I have access to both projects 1. When looking at the deploy keys on "project_b" I cannot remove it, only disable it 1. When looking at the deploy keys on "project_a" I _can_ remove it. _However_, when I successfully removed "newkey" from the deploy keys interface of "project_a". It didn't actually destroy the key, and instead seems to have unlinked it from the project. ### What is the expected *correct* behavior? I expect that they key should be removed, or that there should be an admin-only way of completely destroying any deploy key. Right now it seems the only way to do so is in the rails console. P.S. this might be more of a feature request, so please let me know if I've mislabeled this.
