Add cfg(test) to mod tests in mem_table.rs.

The tempfile dependency causes build failure due to being in dev-dependencies. Adding cfg(test) fixes the isseue.

I would prefer adding it before “mod tests”. Would you please fix it (both in starter code and reference solution)? Thanks!

Looks like it was only missing from the mod tests; in the starter directory.
