'Remove All entries from this domain' on history item does not work as expected

[fnkkio]

Steps to reproduce:

1. Navigate to some website (ie. digi24.ro); at least 2 entries are added to history (ie. http://digi24.ro and http://www.digi24.ro).
2. Right click one of the entries and select 'Remove All entries from this domain'

Result: Only one of entry is deleted.

Expected: All entries from the domain are deleted. (ie. both http://digi24.ro and http://www.digi24.ro)
