fix: Back from Settings no longer lands on a delete wallet screen left by the gear (closes #480)

Leaving the delete wallet or lost-password screen drops its wallet
selection, but the settings gear had just pushed the screen onto the Back
stack, so Back from Settings showed a screen whose button could only
answer "No wallet selected for deletion." Each screen's leave handler now
also takes it off the top of the stack, as the private key export and
recovery phrase screens do since
#461. Back from Settings then
stays on Settings once, as it does for the recovery phrase screen.

Jest tests drive the gear and then Back on both screens, and the delete
screen's own Back.

Model: opus-5-5
