Rats 8.1.3 - 1.20

Issue description
When a rat dies with the angel upgrade, the rat's max health resets to the default max health of 8, during and after becoming an angel. This happens with any rat upgrade that increases max health. Adding or removing an upgrade updates it's max health to change to what it should be.
