Check when trying to create a secret that already exists

[yuki]

What happened when a secret exists but anyone tries to create it?

I think that the secret is overwritten, not checked that the secret exists, so you can "delete" a secret when trying to "re-create" it.

See if this is what happens, and if so, the idea is to do this:

• check if the secret exists before creating
• If it exists:
  • open it to edit
• if NOT exists
  • create it as normal
