* fix(support form): fetch projects on mount
The OrganizationProjectSelector was updated to only fetch when opened to
save on API requests. This causes a problem for the Support Form, which
expects the projects to be fetched immediately so it can fall back to
the first project if no project was paused in the URL.
Added a fetchOnMount prop to OrganizationProjectSelector, which defaults
to false, so we can override this behaviour for the Support Form.
* fix(tests): increase timeout on support form tests
