[FIX] mrp_repair: `tax_id` is a many2many
[FIX] mrp_repair: `tax_id` is a many2many

This is related to 3d58cd1ca208997e5f458e6733c06efde208bb97

`compute_all` indeed does expect ids, and not browse records,
but it expects a list of ids for the `ids` parameter, or a single
id, but not `False`.

Besides, `line.tax_id` is a many2many, despite the fact
its naming seems to say otherwise, and therefore `.ids`
should be used in order to pass all the taxes of the line,
not just one.
