Listing tasks by tag doesn't work if a task has the tag as its second tag

I have a list of four tasks:

```
task list

ID Age Project Tags Description Urg
4 4s mini-game create jumpy ducky mini game 0.8
1 14h party-game hazard-play mini-game create UI/inventory for player 1.9
2 14h party-game hazard-play mini-game create level tile map 1.9
3 28min party-game general add controller support (automatic and manual selection) 1.8

```

I have 3 tags:

```
task tags

Tag Count
general 1
hazard-play 2
mini-game 3

```

I can effectively filter by the `hazard-play` tag:

```
task tag:hazard-play list

ID Age Project Tags Description Urg
1 14h party-game hazard-play mini-game create UI/inventory for player 1.9
2 14h party-game hazard-play mini-game create level tile map 1.9

```

Filtering by the `mini-game` tag only shows the task (4) where mini-game is the only (or first) tag in the list and does not show tag ID 1 and 2 as I would expect:

```
task tag:mini-game list

ID Age Tags Description Urg
4 1min mini-game create jumpy ducky mini game 0.8

```

Reproduce the behavior with the shown task records, then start at the CLI handling for `task tag:mini-game list` and trace how multiple tags are matched. Compare it with `tag:hazard-play` filtering and add coverage for a task whose requested tag is second; done means both matching tasks appear in the result.
