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

[sashachabin]

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

Now deepEquals: 
    await getBrowsers('>0.1% and <10%, dead', 'FR'),
    await getBrowsers('>0.1% in FR and <10% in FR, dead', 'FR')

• Added getQueryWithRegion(query, region) for modify query. Convert popularity expressions to popularity_in_place
• Added getQueryFromQueryParsed. It's browserslist.fromParse for browserslist.parse
• Added a test to check the query conversion
• Return updated query in JSON response

Additionaly

• Update test different coverage statistics for another regions
• Replace unused alias Global to alt-ww

>1% should show the same browsers list on any region value. Otherwise, user will not understand that we change their input.
