Always update player armor metadata

[sjdawson]

This goes hand-in-hand with my PR to fix the initial armor saving when item is used: qbcore-framework/qb-smallresources#497

Also fixes qb-smallresources/195

Moves the update of the player's armor outside of the multiple if checks that wouldn't trigger if only the player's armor takes a hit. Now it will always update the player's armor metadata value if their armor value has changed from the last iteration.

Questions (please complete the following information):

• Have you personally loaded this code into an updated qbcore project and checked all it's functionality? Yes
• Does your code fit the style guidelines? Yes
• Does your PR fit the contribution guidelines? Yes
