Call getSettingsAndNavigate less often

[myxmaster]

Description

Before, getSettingsAndNavigate() was called everytime Wallet.tsx gained focus. Since processing getSettingsAndNavigate() takes some time, this resulted in the app not being responsive for a short time. Example: When you closed the menu and then immediately clicked on a balance slider, it was not responding.

With this PR the flow is optimized, so getSettingsAndNavigate() is only called:

• via handleFocus():
  • On initial load (using existing initialLoad state)
  • When coming from Lockscreen after logging in (using new triggerSettingsRefresh flag)
  • When POS was enabled (using new posWasEnabled flag)
• via handleAppStateChange():
  • when app comes from background (no PIN/password configured)

Additionally fixed a bug, where autonavigation into POS didn't work in this edge case:

• Configure a PIN/password, enable Require login after app returns from background
• Enable POS and leave menu (autonavigate works)
• Disable POS and leave menu
• Put the app in background and reopen it, log in
• Enable POS and leave menu
  => no autonavigate is happening

Root cause was in Lockscreen.tsx, now it is only setting posStatus to 'inactive' when POS is actually enabled.

[myxmaster]

Now using observable flag again, because:
When "Require login after app returns from background" is enabled and you are not in Wallet view (e.g. Menu), then put app to background and reopen, then Lockscreen will not navigate to Wallet, but to Menu... Now the observable triggerSettingsRefresh will be set to true, and when you close the Menu, it will trigger getSettingsAndNavigate().

Removed all the unused route params.

Now triggerSettingsRefresh flag is set at central point in SettingsStore's updateSettings().

(rebased as well)
