Fixes for reported bugs

[JamesSmartCell]

• Crash when getting top activity if app isn't running (WalletConnect V2)
• Crash when attempting to start price alert service (note this is a band-aid, it doesn't have any negative side effects only that a service (price alerts) that caused the app to crash on that device now simply may no longer function).
• Remove WalletConnect V1 connection monitoring (which was causing issues on some phones).
• Add notification alert limiting for already active notifications.
