Make Model#reload more resilient against errors.

Connection errors had the behavior of failing catastrophically, which had
some rather unpleasant implications for things like Model#wait_for, which
implicitly reload repeatedly without any protection.

This change may be better suited to special cases (e.g. Model#wait_for).
