fix(migrations): keep every payment method type in use

Production allows edc and delivery payment methods through a
payment_methods_type_check changed outside the migrations, and has rows of
both. 000094 rewrote the constraint with only cash, card, digital_wallet and
point, so it failed on production (in its transaction, leaving the database
dirty at 94 with nothing applied).

000094 now keeps edc and delivery, down included, and also allows qr, which
the code accepts but no constraint did. 000098 sets the same list where the
old 000094 already ran, as on staging.
