The chart_all method won't chart surfaces until the player has teleported to them, even when the surface name is specified.

Reproduction steps:

1. Start a new freeplay scenario with default settings.
2. Create a new surface and try to chart a large area:
3. /c game.create_surface("test")
4. /c game.surfaces["test"].request_to_generate_chunks({0, 0}, 20)
5. /c game.player.force.chart_all("test")
6. /c game.player.teleport({0, 0}, "test")
7. Open the map and notice that only a tiny area is charted.

No chunks have been generated so no chunks will be charted.

The chunks are definitely generated, with the following evidence:

1. There is perceptible lag when request_to_generate_chunks is called with a large radius like 20 chunks.
2. The on_chunk_generated event is raised for those chunk positions.
3. The function is_chunk_generated returns true for those chunk positions.
4. Using chart(surface, area) instead of chart_all(surface) yields the expected result. The attached video shows the difference.

But if I teleport to the surface before chart_all() is called, then it does chart all of the chunks:
So the behaviour between chart() and chart_all() differs depending on if I go to the surface beforehand, which is unexpected and I would say a bug.

Thanks for the report. This is now fixed for the next release.
