Error attempting to alter the 'collection_products' view when it is not set

Problem/Motivation

I receive the following error multiple times when visiting the view or recreate page for a feature that contains default views:

Notice: Trying to get property of non-object in commerce_kickstart_taxonomy_views_default_views_alter() (line 208 of /var/www/html/profiles/commerce_kickstart/modules/commerce_kickstart/commerce_kickstart_taxonomy/includes/views/commerce_kickstart_taxonomy.views_default.inc).

Features appears to be calling the hook_views_default_views_alter() hook for each module with only that modules default views set in the $views variable rather than calling the hook once with all default views for all modules. I could see where this could be done by other modules as well, so we should check that a view exists before trying to alter it.

Proposed resolution

Check that the 'collection_products' view exists before attempting to alter it.
