[FIX] purchase: Wrong statistics RFQs Sent Last 7 Days

Issues
------
Purchase Dashboard gives wong value for PO in RFQ and RFQ sent when
user's language is not English

Current behavior before PR:
---------------------------
1. Create some RFQ and RFQ Sent to see its statistic in dashboard
2. Swith user language to another one that is other than English
3. Statistic in the dashboard is wrong now

Solution
--------
Passing translated RFQ and RFQ Sent into the dashboard query in stead of
passing pure text without translation.
