Filtered search bar assigned to me option

Description

We recently added assigned to me as a dropdown option for the filtered search bar (only available on master at the moment). That was before we rearranged the dropdown so that the current user is always on the top of the dropdown. Now that we have both current user as the top selection and a static assigned to me option, it is starting to look a little redundant.

In this screenshot, the current user is root

Proposal

I am proposing 2 options.

1. Remove assigned to me option from the assignee dropdown
2. Add authored by me option for the author dropdown to be consistent
