Lockwise not locking after force closing with Greenify (root mode)

[kbrosnan]

Copied from https://bugzilla.mozilla.org/show_bug.cgi?id=1649384

Steps to reproduce:

Greenifying Lockwise or force closing it after unlocking the app, as long as this is done before the chosen timeout.

Actual results:

After reopening Lockwise, passwords are unlocked.

Expected results:

My passwords should be locked with my fingerprint/PIN. I have my timeout set to one minute, autofill and unlock with fingerprint disabled. If the app gets "force closed", the vault should be locked as soon as it is resumed. This probably applies to crashes as well.
