Summary	0011323: Cut-off delays get applied to / inherited by another instance if they share one bank account in common
Description	Just reproduced using TOPS/CHF stage and private taler.hacktivism.ch instance, both using exchange.taler-ops.ch, that is on two instances running on completely different infrastructures and with different versions of the taler-merchant, such that this must be an exchange issue. Highly problematic is, that the correct cut-off dates are only shown for the instance they were set on; the other instance continues to display the old ones -- in the UI at least, but behaves differently than shown. This should be fixed as to not have instances inheriting cut-off delays because of a common bank account (e.g., IBAN no.).
Steps To Reproduce	0. Add one common bank account to an instance A and B, both using the same exchange. 1. Add a second bank account to an instance B, do all three KYC Auths (1 for A, 2 for B). 2a. Change the payment delay to 1s for instance A, having only one bank account; making a payment practically impossible, transaction gets cancelled ("already claimed"). 2b. Also in instance B, it won't be possible to do any payment, because payment delay is too short; this without touching instance's B settings at all. Instance B can even be running on another site, by someone else. 2c. This sticks true for B, even if another bank account is defined for wire transfers using the transfers location: $site/webui/#/transfers; this makes it for B not transparent what's going on / why payments eventually don't work at all (or if they work, with other delays not visible and not set oneself).
