Various fixes

[NicoPennec]

Problem

• The Task page can fail to load data (see #1512)
• On the Task side panel, from the My Tasks page, some links can use the wrong production ID.
• Some edge cases of undefined values can crash Kitsu UI.
• Some outdated npm dependencies.

Solution

• Fix data initialization on the Task page, when the production ID changes.
• Fix links from pages without current production defined.
• Fix some edge cases of accessing undefined values, by checking if is nullish or using optional chaining
• Bump outdated npm dependencies.
