fix error message when buying land

[X1Vi]

This PR closes issue #15178, which is the error message not showing up when the player is buying land but has insufficient funds.

Now there is an error pop-up when the player try's to buy land when having insufficient funds.

You should probably have a look at #15224, as the discussion there is also relevant to this.

Ok, if you or the team needs any changes done do ping me.

Worth having a read of the wider issues too, and think about whether this fixes all object/buy land issues and whether it increases consistency of behaviour with other tools: #15216
