TaskList menu split

[opatry]

Description

As what Google Tasks Android app does, and given there is more room in our context compared to Web UI task list columns, it's nice to extract some actions from the task list more menu.

Sorting is then now a drop menu menu on its own near the more menu to reach edit actions.

• Split task list menu in 2
• Extract each edit menus in their own components
• Extract task list TopAppBar in its own component
• Use menu icon depending on current task list sorting
• Add UI tests for both menus
• Add UI tests for task bar
