Include an optional hook_update_N() to remove any existing redirects

Problem/Motivation

Enabling pathauto and redirect module and setting redirect to " Automatically create redirects when URL aliases are changed." (default behaviour), change a node's url from (original) to (something else). Then, change the node's url back to (original). Result: Infinite loop warning appears on node access.

Proposed resolution

Include an optional hook_update_N() to remove any existing redirects that uses the same approach as https://www.drupal.org/node/2336357.
