This fixes an issue when a one2many computed field is recomputed: all computed
lines are created twice.
Consider a simple case, where the value of the field is a single line. The
execution goes as follows:
* invoke `recompute()`
* write value `[(5,), (0, 0, vals)]` to the field
* command `(5,)`: invoke `unlink()`
* delete existing lines
* invoke `recompute()`
* write value `[(5,), (0, 0, vals)]` to the field
* command `(5,)`: invoke `unlink()`
* no more existing lines, return
* command `(0, 0, vals)`: invoke `create()`
* create a new line
* mark the field as recomputed
* command `(0, 0, vals)`: invoke `create()`
* create a new line
* mark the field as recomputed
There is a recursive call to `recompute()` inside `unlink()` that recomputes
the field while it is being written. The fix simply prevents the recursive
call to `recompute()`, just like in methods `create()` and `write()`.
