Pins published to Connect sometimes include username in name and sometimes do not

[juliasilge]

When you write a pin to Connect, the displayed name changes depending on whether the last write did or did not include the username.

i.e. this reflects me doing pin_write(board, x, "fabulous_numbers") and pin_write(board, x, "julia.silge/superb_numbers"). I can change how either one displays by including (or not including) my username. I believe we should always include the username rather than switch back and forth.

As a reminder, pins for Python requires Connect users to include their username when writing and does not try to look up who they are.

This happens because default_title() gets called before any board-specific methods:

We don't have a chance to check/change name before the metadata is set up.
