TPoS contract not displayed when being your own merchant

[hermesesus]

Description

When being your own merchant (self TPoS), i.e. when using the same wallet as owner and as merchant, the TPoS tab stays empty, the TPoS contract isn't displayed.

Expected behaviour

TPoS contract should appear in the TPoS tab.
The "1XSN" used for the TPoS contract should be locked (cannot be spent) in Coin selection (Coin control).

Actual behaviour

TPoS contract isn't displayed in the TPoS tab.
The "1XSN" used for the TPoS contract is unlocked (can be spent).

How to reproduce issue

Make a TPoS contract where the merchant address and the TPoS address are generated on the same wallet = self TPoS = being your own merchant.
