[FIX] procurement: missing variable

scheduler_cron_id was not initialised so the scheduler always crashed (with just info message)
[FIX] mrp: duplicated find bom buttons

The product_id field is not required on a mrp.bom (while product_tmpl_id is). When searching for BOMs linked to a product.product, we should display the one specific to this product and the ones linked to the template (but not linked to another variant).

[FIX] website_sale and point_of_sale fixes
[FIX] sale/website_quote: inherit the sale order report to show the validity date
[REF] mail: same_thread field changed into no_auto_thread, its contrary, to avoid migration issues (adding a 'always False' column is easier than an 'always True').
[FIX] module loading: manual x2x fields can now refer to manual models

The fix consists in this: when setting up models, ignore manual fields that
refer to unknown models if all models have not been loaded yet.
[FIX] survey: missing timezone conversions

As the survey hardcode lot's of views and reports in python, we do not beneficiate from automatic timezone conversions in the webclient.
Hopefully this is fixed in v8 after refactoring of the survey module. opw 608786
[REF] website_quote: displayed string of validity_date field changed from 'Validity Date' to 'Expiry Date'
[FIX] models: default_get() shall not return a dict as a many2one value

When a new record is returned as the value for a many2one on a new record, the
method Many2one.convert_to_write() now returns a NewID, and default_get() then
discards that value from its result. This makes it consistent with its former
behavior.

[FIX] mrp: better selection of bom

When searching for a bom based on a product.product, the method used to return any bom linked to the template (so searching for bom for variant A could return bom for variant B if both share the same product.template).
This will allow to return bom not linked to a variant without returning the one of another variant (opw 609358)
