Reviewers

Django Evolution 2.1.3 introduced a patch for modern versions of
mysqlclient on Django < 2.0. The patch tried to handle the situation
where mysqlclient wasn't installed, but it didn't catch the right
exception.

This change adds a more broad exception handler, and also exception
handlers in the patch loader, one wrapping needs_patch() and one
wrapping apply_patch(). This will help us avoid other unforeseen
issues in the future.

Ran all unit tests without mysqlclient installed.
