[Bug]: Back button navigating after scanning QR closes Bitkit instead of closing bottom sheet

[catch-21]

Describe the bug

Using the generic QR scanner, after scanning an address or invoice a bottom sheet opens showing the Bitcoin Amount or Review & Send screen respectively. At this stage, if the hardware back button is used Bitkit closes. This is different to using any option from the Send menu (e.g. Enter Manually and Scan QR), which navigates to previous screen as expected.

Reproduce

1. Tap on the QR scanner (bottom centre of home page)
2. Scan a Bitcoin address or LN invoice QR
3. Use hardware back button (possibly android only)
4. Observer Bitkit closes
