[FIX] api: avoid to return all fields *2many in onchanges

When an onchange returns a change in a 2many field line (a '1' tuple, update), avoid to return all fields of the *2many field but only the altered field.

Otherwise, the web client regard all the fields of the 2many as dirty, and try to write on all fields (even if the value is the same, thus)

[FIX] tools: find_in_path: config is not ready at import time

commit f76d4525a was not actually working: extra keys from
config files are not yet into the config options dict at
import time. The fix is to move the logic inside the method,
like in `find_pg_tool` just below.

Also fix the use of `find_in_path` in report.py: the subprocess
may also raise AttributeError exception, so instead of listing
all the possible ones just re-raise the IOError shallowed by
`find_in_path` when the result is None.

[FIX] product_extended: price from bom is build for product templates

As it sets the standard_price field, which is defined on product templates only: setting the standard price of a product variant will lead to set the standard price to all the variants of the product template.

There is therefore no meaning to compute and set the standard price of product variants according to the boms
