Better assignee history in issue

Description

We can see information about changes of assignee on already created issues.
I mean this:

Lukasz Sabiniok @loockass assigned to @SOMEONE 4 days ago

But there is no information about original issue assignee if he or she was assinged during issue creation and then changed.

Proposal

Change message added after reassignment to something like:

Lukasz Sabiniok @loockass changed assignee from @SOMEONE to @someoneeelse 4 days ago

Or / and show somewhere in issue view full history of assignees.
