BookmarksRunner: Avoid multiple connections of identical signal

The factory returns the same object when the browser name is not changed.
Connecting the signal again leads to multiple calls to the slot each
time the signal is emitted.

Test Plan:
1. Add some debug output to the teardown() slot
2. Open the krunner multiple times and enter some query
3. teardown() is called exactly once
