[FIX] stock: no early currency rounding when computing average price

It is a common need to set a higher decimal precision
for `Product Price` (i.e. the product cost field) for
high volume / low value items. This may typically
require up to 4-6 decimals for e.g. EUR/USD-based
companies where the currency has 2 decimals.
In that case the product cost should be stored with
full precision without applying the currency rounding.
The appropriate currency rounding will be applied
anyway as soon as a transaction actually uses that
product cost (typically in a SO/PO)

[FIX] purchase: analysis view must not group by quantity, otherwise identical PO lines are counted only once

The product quantity is one of the columns that must be
aggregated, not used to fold PO lines into the same
result row.
This, combined with missing aggregation operators
was causing multiple identical PO lines from the
same PO to be merged together and only counted once
in some aggregations.

[FIX] sale,sale_stock: sales analysis view using incorrect JOIN and group by clause

Similarly to the recent fixes in Purchase Analysis,
the Sales Analysis view must not group on the quantity
field. It is one of the columns that must be aggregated,
not used to fold PO lines into the same
result row.
The line count was also incorrect because of this, and
had to be corrected to actually count() the underlying
SO lines.

In addition, the JOINs were done in the wrong order,
which could cause problems (e.g. if an empty SO ever
landed in the database, all the SO line columns
would be empty in the JOIN, and cause errors)
