Fix entry sorting by title

[varjolintu]

Fixes Sort matching credentials by title.

Description

Previously sorting by title didn't sort usernames after the title sort, and the order was not reverse but mixed. The sort provided the following results:

c_username (title1)
z_username (title1)
a_username (title1)
z_username (title2)
c_username (title2)
a_username (title2)
...

After the fix:

a_username (title1)
c_username (title1)
z_username (title1)
a_username (title2)
c_username (title2)
z_username (title2)

If the titles are identical another compare is made based on the username.

How has this been tested?

Manually.

I would also add this PR one more thing: remove the URL compare to the entry title. That doesn't make any sense. If I have an entry to a totally different site, but for some reason the entry title contains that site, the credentials are returned for that entry too.
