[FIX] safe_eval: no shadowing of PostgreSQL's exceptions

Letting PostgreSQL low-level exceptions bubble up
ensures that the mechanism for automatically
retrying transactions will work.
In case of transient errors such as deadlocks or
serialization errors, the transaction will be
transparently retried. Previously they were
transformed into ValueError and caused a permanent
failure immediately.

The fallback to ValueError is meant for invalid
expressions or expressions that use variables not
provided in the evaluation context. Other
exception types should be preserved (this is
further improved in Odoo 8)
