Expected Behavior

The KeePassHTTP plugin returns matched entries only

Current Behavior

When the title or URL field in an entry contains an invalid URL, the entry is returned

Possible Solution

Reject invalid URLs in Service::matchUrlScheme() (untested)

Steps to Reproduce (for bugs)

1. Create an entry with title https://example.com foobar. Note that there's a space before foobar
2. Check matched entries from KeePassHTTP in browsers
