Show current user immediately in filters

Description

I pretty often use filters to find issues authored by myself or assigned to me.
But if I click to a filter, I have to wait seconds just to see a fulfilled dropdown with many users that I don't need.

Proposal

• Show current user immediately in assignee and author dropdown while other members are being loaded via ajax.
• This applies to the project issues list search bar, the project merge requests lists search bar, and the issue boards search bar (both the regular view, and the modal view of the issue board when you click Add issues).
