fix(appcomposer): add refresh fallback (#1507)

JLargent42 · Jacob Largent · web-flow · commit ecd6be817628 · 2023-11-24T13:04:54.000-08:00
Problem:
If Composer fails to load, the user has to restart their IDE
to be able to use Composer.

Solution:
This adds a basic retry when the user opens Composer and the
page hasn't already been loaded.
