fix: project query controller logic

[ruthra-kumar]

Fixes broken/incorrect results on 'Project' field in Sales Order and Delivery Note.

Issues addressed:

1. Completed/Cancelled project's are returned in result
2. Projects aren't filters on Customer, even after selecting it in form

status and customer filters are set in Sales Order and Delivery Note.
However, Sales Invoice, Purchase Order and Purchase Invoice function as before.

Is that intended?

Yes. This PR is only to address the broken sql query in queries.py.
Ex: Status and Customer was filtered with an OR condition by the searchfields logic, which led to cancelled/completed projects or customer filter not being applied as intended.

	searchfields = frappe.get_meta(doctype).get_search_fields()
	searchfields = " or ".join(["`tabProject`." + field + " like %(txt)s" for field in searchfields])

However, Sales Invoice, Purchase Order and Purchase Invoice function as before.
Is that intended?

For SI, PO and PI's, simply adding a set_query should be enough now, which is to be done in a separate PR
