Issue Details

Steps to reproduce:

1. Open "Recent activity"
2. Find a request of type "HTTPS Tunnel" or "Connection"
3. Uncheck "Apply only for package name" checkbox
4. Then check it again.

Expected Behavior

On step 3 you should have a simple rule looking like this: ||example.org^
On step 4 you should have a rule with $app modifier only: ||example.org^$app=packagename

IMPORTANT: $domain modifier can only be added if a request has Referrer URL. If this field is missing, there should be no $domain modifier.

Actual Behavior

On step 3 the rule has $domain modifier which makes zero sense for these requests: ||example.org^$domain=example.org
On step 4 the rule has both $domain and $app modifiers: ||example.org^$app=packagename,domain=example.org
