Use exceptions when enabling case component / checking for 'CREATE VIEW' permissions

[mattwire]

Overview

See #18466. This removes another use of ignoreException(). In this case the civicrm/admin/setting/component form was hanging because ignoreException() was not enabled and the DB error exception was not trapped. This fixes that and removes ignoreException() from the enable case function.

To test, remove "CREATE VIEW" permission from your mysql user. It is clear from the comments that this code was never working very well.

Before

ignoreException() used when testing for/creating views.

After

Exceptions thrown and feedback provided to user.

Technical Details

Explained above.
