Intermittent issue with DevHub pubkey not registered in Lair

[matthme]

Describe the bug
The following can sporadically occur after setting up a new Launcher profile:

1. Set up password and initialize lair
2. Installing DevHub (automatically)
3. From then on, zome call signing consistently fails in the DevHub with the error "Query returned no rows" that's thrown by the sign_by_pubkey function of the lair client.
4. Apps installed afterwards from the filesystem work fine, no zome call signing errors

In this case, the only thing that helps is a factory reset and some luck that the same thing does not happen again.

Additional context
In a case where this occured, I checked the keys stored in Lair via list_entries() and verified that the DevHub's public key is missing.
