Correctly map lastRequest timestamp

Browse Source 
The lastRequest timestamp is changed to show the last request to a
pricenode.

The previous approach of using the "last provider request timestamp"
does not make sense in the new setup. Each currency rate is based on
rates from several providers, each with their own "request timestamps".
In addition, the pricenode returns the timestamp each rate was
calculated. On top of that comes the timestamp when the Bisq node
queries the pricenode.

Since what is most relevant for the Bisq node is the "freshness" of a
specific rate, the timestamp most indicative of that is the moment when
the pricenode is queried.
