(Re-) calculate taxes for new renewal orders

[dennisnissle]

Description

When (automatically) adding a new renewal, taxes for the corresponding renewal order should be recalculated. Tax rates in WooCommerce may be subject to change, e.g.:

• VAT rates may be reduced for a certain amount of time
• VAT rates may change, increase, decrease for certain countries

Is there any reason why taxes are not being (re-) calculated for renewals based on the current settings? For orders where prices do not include taxes this may lead to higher/lower total prices but nevertheless taxes would at least be precise and not wrong.

Testing instructions

1. Create a new subscription
2. Update a tax rate, e.g. change percentage
3. Generate a renewal for the old subscription
4. See how the renewal does not reflect current tax rates.

@haszari We have a merchant in #7524212-zen whose subscription initially included VAT. The subscription was paused then restarted. Upon renewal, VAT was added in addition to the initial cost. Is this a bug?

@diegocurbelo / @Automattic/quark are best to answer your question @ChrissiePollock !

The merchant in 7524212-zd-a8c confirmed it's not on us, the culprit was one of their premium plugins.
