What does the PR do
Closes #16994
Check if something has actually change in prices before reseting the wallet.
This would be the first line of defense for token prices updates. It seems to be enough for the send modal performance improvements.
The full solution to this issue (and maybe to a lot of wallet related UI perf issues) would be to send granular QML updates only for values that have actually changed. But this implies extensive nim+qml refactoring.
