Fix around player → country scope change bugs (Fixes #7)

[PulseLane]

Changing the scope from "Around me" to the country filtering will result in some inconsistent behavior. None of the scores will load and the up/down arrows on the side on the leaderboard are not properly updated. This is caused by the AroundPlayer hardcodes only checking that the scope matches; however, country filtering is implementing using a bool override for the current scope.

• Add a check that _filterAroundCountry is not true when checking that the scope is "AroundPlayer"

Fixes #7
