desktop M10.4: fix stmt lifetime in reminders/search

Both chained `stmt.query_map(...)?.collect()?` as the block's tail expression,
so the prepared statement (a block local) was dropped before the borrow held by
the mapped rows ended (E0597). Bind `let rows` first, matching every other query
in the file. rustc error, so this also unblocks test + the release build.
