Fix migration v292

[lunny]

Fix #29874 (comment)

• The migration of v292 will miss many projects. These projects will have no default board. This PR introduced a new migration number and removed v292 migration.

• This PR also added the missed transactions on project-related operations.

• Only SetDefaultBoard will remove duplicated defaults but not in GetDefaultBoard

I believe I still have an issue with the new migration. It says: "Ensure every project has exactly one default column". It tries to do some SQL queriy on the project and project_board tables. Migration seems to fail with error: pq: invalid input syntax for type bigint: "true". Help?? I'm stuck on this 293 migration. My docker container keeps restating in a loop now. This happens after I updated to v1.22. On version 1.21 everything worked fine. Migration 293 is failing for me!

I'm using Docker gitea/gitea:latest-rootless image with PostgreSQL v14.

When I currently dump the project & project_board schema, it looks like this (hope this helps):

Project table:

CREATE TABLE "public"."project" (
    "id" bigint DEFAULT GENERATED BY DEFAULT AS IDENTITY NOT NULL,
    "title" text NOT NULL,
    "description" text,
    "repo_id" bigint,
    "creator_id" bigint NOT NULL,
    "is_closed" boolean,
    "board_type" bigint,
    "type" bigint,
    "created_unix" bigint,
    "updated_unix" bigint,
    "closed_date_unix" bigint,
    "card_type" integer DEFAULT '0' NOT NULL,
    "owner_id" bigint,
    CONSTRAINT "project_pkey" PRIMARY KEY ("id")
) WITH (oids = false);

Project board table:

CREATE TABLE "public"."project_board" (
    "id" bigint DEFAULT GENERATED BY DEFAULT AS IDENTITY NOT NULL,
    "title" text,
    "default" bigint DEFAULT '0' NOT NULL,
    "project_id" bigint NOT NULL,
    "creator_id" bigint NOT NULL,
    "created_unix" bigint,
    "updated_unix" bigint,
    "sorting" integer DEFAULT '0' NOT NULL,
    "color" character varying(7),
    CONSTRAINT "project_board_pkey" PRIMARY KEY ("id")
) WITH (oids = false);
