[Bug] 2.4.0 Errors with 12 word Mnemonics, Regression in 2.4.0 as no errors in 2.3.1

[BrandtH22]

What happened?

Initially reported by Nektodron in discord: https://discord.com/channels/1034523881404370984/1034870571864948777/1255165575597129788

Current workaround: downgrade to 2.3.1

Confirmed this is a regression in 2.4.0 as the below process works without error in previous versions.

Error: "Cannot read properties of undefined (reading 'pk')"

Steps to reproduce:

1. import 12 word mnemonics
2. Click logout
3. Select the 12 word mnemonic keyset and click Details
   The imaged error will appear when the above is performed in 2.4.0 but in previous versions it properly displays the key information

Version

2.4.0

Error in GUI seems to be due to the keyring not properly identifying the farmer or pool public keys:

When that same keyset is loaded in 2.3.1 they are present (and there is no error in the GUI):

Chia version: 2.3.1

Note that a testing keyset was used for this so no concerns on keys being leaked.

Steps to reproduce the above:
NOTE- I did not re-import keys when switching versions.

• install 2.4.0
• import a 12 word mnemonic
• 2.4.0 has errors in the gui and cli does not show farmer or pool public keys
• uninstall 2.4.0
• install 2.3.1 (note keys are left entirely alone in this process)
• gui works as intended and pool plus farmer keys show in cli

Can confirm that #18246 fixes this issue 👍
