[FIX] account_asset: moves should use the depreciation line date
[FIX] web: FieldMany2ManyBinaryMultiFiles must extend ReinitializeFieldMixin

The add attachment button should be displayed while being in edit mode, but not in view mode
As the widget depends on the form actual mode, the widget should be re-rendered each time the actual mode changes

This is the point of the ReinitializeFieldMixin class
[FIX] web: many2many_binary widget upload

once widget extended with ReinitializeFieldMixin, the event binding with the binary file input and the on_file_change method can be done in initialize_content instead of start

[IMP] stock: added missing 'context' parameter (opw 616952)
[FIX] project_timesheet: missing timesheet for tasks without project

Timesheet activities (hr.analytic.timesheet) are generated when a work activity (project.task.work) is logged on a task.
These are updated if the project of the task is modified.
This patch applies the same behaviour for tasks without project, the timesheet activities are generated once a project is set on the task.
To avoid redundency in the code, extract the computation in a distinct method.
