[FIX] sale: Apply several fix on sales tour

1. Lead to loose the tour: Remove the step of the tour that asks
to set an address (the address is auto-completed at free trial
based on domain name).

2. Bug: At step 3, it redirects to the
invoice settings to select a localization, when you click on
"install more packages", you are sent back to the sales app.
--> this bug is related to res_config_settings.js from base addon.
I tried to fix this bug by adding a data-attribute "discard" in the
res_config_settings_views and checking this additional condition in
the js.

3. Bug: Tour blocks at last step "send by email" on quotation.
After clicking on "sent" on the pop-up, there should be rainbow
effect to mark the end of the tour.

4. Bug: Sale order line: fix the blue color on Invoiced Quantity
only, instead of the full line

5. Put the "sample product" in active= false (it's necessary for
the sample invoice but should not be visible to the user, they
should create their own)

6. Merge the 2 dates fields related to expected delivery on sale.order
--> since other modules extends this module, I made the field
expected_date invisible and put the same value in both fields. This
value is the max of the order_lines.expected_date
