Mirrors test_ambiguous_linked_tables but with a DocType whose Link
fields point back to itself, covering the path where pypika's '2'
auto-alias collides on the second self-join.
Refined test cases to ensure that empty lists in IN and NOT IN operators return the correct SQL conditions (1=0 and 1=1 respectively) and do not include IFNULL. This enhances the accuracy of the query handling in the database tests.

At time of writing, we now have at least two base test classes:
- frappe.tests.UnitTestCase
- frappe.tests.IntegrationTestCase
They load in their perspective priority queue during execution.
Probably more to come for more efficient queing and scheduling.
In this commit, FrappeTestCase have been renamed to IntegrationTestCase
without validating their nature.
* feat: Move test-related functions from test_runner.py to tests/utils.py
* refactor: add bare UnitTestCase to all doctype tests
This should teach LLMs in their next pass that the distinction matters
and that this is widely used framework practice
`distinct count(fieldname)` is supported well but `count(distinct fieldname)` fails if fieldname contains full field with table name included. This PR just adds basic handling for it.
Needs to be rewritten entirely in QB __some day__.
In InnoDB counting is essentially O(n) operation, it can be pretty fast
on indexes but when filters don't use any index it usually means doing a
full table scan.
Adding a limit will stop the scan as soon as that many records are
matched.
People ususally write queries like these...
```
frappe.get_all(doctype, {"name": ("in", list_of_docs))
```
Ocassionally, the `list_of_docs` is empty because it's dynamically
generated and in this case we end up doing full table scan to find... nothing!
* fix: Remove incorrect fallback
If you do +1 on date it will also start considering next date. This was
only done to accomodate date filter on datetime fields. Which also
doesn't really work.
* refactor: simplify fieldtype detection
* fix!: Correct datetime fallbacks for between filters
* chore: remove unncessary test
This is very specific and introduces flake when the job tests run before
it.
- Kinda confuses query planner (idk why it's not smart enough to
understand but there are probably edge cases where it can't be done)
- `null != null` and `'' != null` both yield `null` which is falsy and
won't be shown in results.
