On a saved-filter (or view-filter) kanban view, checkBucketLimit counted
the total number of tasks matching the filter instead of the number of
tasks actually in the target bucket. Adding the first task to an empty
limited bucket was therefore wrongly rejected with code 10004
"exceeded the limit", even though the bucket was at 0/limit. The same
setup on a regular project bucket worked because that branch counts
task_buckets rows scoped to the bucket.
Scope the count to the bucket by adding `bucket_id = <id>` to the
TaskCollection filter. ReadAll combines this with the saved-filter /
view filter, so the count reflects exactly the tasks that are in this
bucket and match the filter. This keeps the #355 behaviour (stale
task_buckets rows whose tasks no longer match the filter are excluded)
while fixing the unscoped over-count.
Fixes#2672
Two categories of fixes:
1. Use defer s.Close() instead of explicit s.Close() to prevent session
leaks when require.FailNow() triggers runtime.Goexit(), which skips
explicit close calls but runs deferred functions. Leaked sessions
hold SQLite write locks that block all subsequent fixture loading.
2. Add s.Commit() before db.AssertExists/db.AssertMissing calls. These
assertion helpers query via the global engine (not the test session),
so they cannot see uncommitted data from the session's transaction.
For block-scoped sessions (kanban_task_bucket_test.go), wrap each block
in an anonymous function so defer runs at block boundary rather than
deferring to the enclosing test function.
BREAKING CHANGE: The bucket id of the task model is now only used internally and will not trigger a change in buckets when updating the task.
This resolves a problem where the task update routine needs to know the view context it is in. Because that's not really what it should be used for, the extra endpoint takes all required parameters and handles the complexity of actually updating the bucket.
This fixes a bug where it was impossible to move a task around between buckets of a saved filter view. In that case, the view of the bucket and the project the task was in would be different, hence the update failed.
