Fixes: #926.
Gas estimations were not being decoded correctly (indicated with "error getting gas price predictions" in the console) and were preventing transaction dialogs from continuing past the step containing the GasSelector component. This affected mainnet only, because in testnet we have hardcoded gas prices (for when the gas prices on mainnet are insane) which is why it was not apparent in testnet.
fix: Contract address not showing correctly
This was caused by `getStickerMarketContractAddress` being moved to `utilsView` but not updated in QML
