Auto add in region to usage stats query with the specified region in the parameter

[sashachabin]

It seems that a rather particular scenario, when the user writes >0.1, selects a region. And we need to automatically add the region to users query.

• Add in .. region to the query if specified region parameter
• Return updated query in JSON response
• Write tests getBrowsers(query, region)
  • ShoulddeepEqual:
    await getBrowsers('>0.1% and <10%, dead', 'FR'),
    await getBrowsers('>0.1% in FR and <10% in FR, dead', 'FR')
  • Queries should show different coverage
    await getBrowsers('>0.1% and supports es6-module', 'alt-as')
await getBrowsers('>0.1% and supports es6-module', 'IT')
