To merge more logins urls by overriding hash

[ICHx]

Thanks for writing the script, this PR aimed to solve duplicates that ain't having same url but the same hostname.

e.g. "https://github.com" and "https://github.com/login" are different items, but we want to treat them as the same

Disclaimer: This implementation is not yet considering same username with different password. This should be some interactive process if required.
