MAE-590: Update payment plan next contribution date on autorenewal

[omarabuhussein]

Before

• For monthly renewals, the new recurring contribution will have the "next scheduled contribution date" empty.
• For annual renewals, the recurring contribution will keep having the same "next scheduled contribution date" it had before renewal.

This happen because the work I did here: https://github.com/compucorp/uk.co.compucorp.membershipextras/pull/389

After

I updated the autorenewal so it work according to the new v5 specs, where for monthly renewals it will be +1 month from the new payment plan last contribution, and for annual payment plans it will be +1 year from last contribution.
