Formerly, if a formatted text component tried to render without the
project config (used by inner linked text components) it would
temporarily fall-back to rendering the unformatted (and un-linkified)
text via `.textContent` -- mirroring the behavior of gr-linked-text.
The result is formatted text elements (when rendered without a project
config) appear as one long line of text. Unlike linkification, however,
text can be accurately formatted with or without the project config --
so this disruptive, poor UX is unnecessary.
The formatted text component is updated to format text when the project
config has not provided, and to re-render when the config has been
provided.
In order to propagate project config loads to the formatted text
components hosted by diff comments, the REST calls must be made by the
diff thread component. To make this call, the thread must have the
project's name, so gr-diff-builder is updated to provide this name to
thread components.
