[Bug]: Migrating the smart transaction opt-in status failing

[racitores]

Describe the bug

When testing feature #28854, we have found that migration from different older version than 12.11.0 aren't getting the expected results (described in the PR)
Basically we have seen that when 12.11.0 is updated the STX value is always enabled.
We need to make sure at least next test works well to be able to ensure the feature is working:
The user has MM Extension <=12.8 installed. They submit a smart transaction (it can fail or succeed). They opted-out for STX with the STX opt-in modal. The user updates MM to 12.11. The modal is not displayed and STX are disabled.

In addition we have noticed that only v12.5.0 shows the STX info popup (where STX setting value is initially setup), while with other versions, this popup is not shown and the STX setting value is set to null (while the UI shows that is activated)

Expected behavior

with next test the STX should be deactivated after upgrading the extension
The user has MM Extension <=12.8 installed. They submit a smart transaction (it can fail or succeed). They opted-out for STX with the STX opt-in modal. The user updates MM to 12.11. The modal is not displayed and STX are disabled.

Steps to reproduce

1. Install extension 12.5 / 12.7.1 / 12.8 (any of them will reproduce the issue)
2. Open the extension, confirm that STX is activated
3. Do a TX on mainnet
4. Change STX setting to disable
5. Upgrade the extension to 12.11.0
