Two versions for details.remittances.title

[davidbauer]

details.remittances.title should be different for total view and country view.

the text "von Migranten in ihre Heimat gesendet" fits perfect for the total view, but could be misunderstood in the single country view (as remittance outflows of the selected country)

for the single country view, details.remittances.title should be something like "von Migranten erhalten"

[davidbauer]

same for details.aid.title, which in its current wording makes sense for countries, but not for the overall view.

Done.
