fix(mobile): load the repo list in GitHub Project mode

loadTasks returned before loadRepos() when the GitHub mode was `project`,
so `repos` stayed empty, `hostedRepos` was empty, and
filterGitHubProjectRowsForRepos dropped every board row. Visiting any
other mode populated `repos` as a side effect, which is why tapping
Issues once and coming back appeared to fix it. The active mode syncs
from the desktop, so a fresh launch can land straight in Projects and
show "No project items" for a board that has items.

Move the project-mode short-circuit below the repo list load. Project
mode still fetches no issues/PRs; it just no longer skips the repo list
it needs to match rows against.

Fixes #12966
