fix(test): sync before searching in second searchEmails IMAP test

The searchEmails implementation now queries local SQLite FTS5 (not IMAP),
so syncEmails must be called first to populate the index. The first test
was already fixed; this adds the same syncEmails call to the second test
and adds a clarifying comment to the implementation.

Closes #506
