Various fixes

[NicoPennec]

Problem

• On the Breakdown page, toggle the casting on Picture mode, select a line with an asset, and click on the "+1" button. The action will fail, and a UUID value will be displayed.
• On the Breakdown page, select two lines in the casting: a line with an item and a line without items, then click on the "-1" button. A silent error will be raised in the developer console.
• On the Task Type page, updating an estimate file will incorrectly update the start/end dates.
• An UX glitch on the user menu in the Japanese language (see When Kitsu is switched to Japanese, a piece of the personal menu remains displayed #1571).
• On the Shot page, In the Casting section, display the Ready For status of a shared asset is not wanted.

Solution

• On the Breakdown page, fix the add/remove one asset action. A wrong parameter could be passed to the method
• On the Breakdown page, fix the remove one asset action with a multiple line selection. Check empty values before run actions.
• On the Task Type page, fix the update of task estimation. Add a missing parameter.
• Fix an overflow glitch when the user menu is closed. Remove the component if closed and use keyframes for the opening animation.
• On the Shot page, hide the Ready For status for shared assets in the Casting section.
