Summary

This change fixes the command arc look remotes for PHP 8.1.

Without this change, the null value bubbles up to PhutilUTF8StringTruncator, reaching a strlen().

This control probably does not need to be done at this low level inside PhutilUTF8StringTruncator,
but it is right to be at this high level from the caller in ArcanistRefView.

Closes T15368

Test Plan

run "arc look remotes"
still works in "old PHP" like 7.4
start to work in recent PHP 8.1+

Hi @Matthew :D super-safe thing here. Do you love this?

@Matthew feel free to "sgtm" <3

I think @speck maybe has better approaches here (do you know arc look? it's lovely)

Any feeling here? @avivey
