implants command experiences consistent failures after specific trigger

[save196]

Describe the bug
The implants command starts failing and returns [!] rpc error: code = Unknown desc = record not found instead of the list of generated implants. The only way I was able to fix it is by removing the ~/.sliver dir.

To Reproduce
I was able to consistently reproduce the issue by running migrate -p <pid> in a session created with service format (I'm not sure if it may happens even under other circumnstances).
Steps:

1. implants -> [*] No implant builds
2. generate --mtls <ip> -l -f service
3. implants -> shows the generated implant
4. (spawn session implant on the target machine)
5. use <session-id>
6. ps
7. background
8. implants -> still shows the list of implants
9. use <session-id>
10. migrate -p <pid> -> returns [*] Successfully migrated to 1120 but doesn't spawn any session
11. background
12. implants -> [!] rpc error: code = Unknown desc = record not found

Expected behavior
Having the list of generated implants from implants.
