Remove ingredient descriptions that begin with the word 'very'

[jayaddison]

Describe the bug
The word 'very' appears as a prefix on some ingredient descriptions, and isn't something that users seem likely to search for when describing their locally-available ingredients.

We should remove it as a named product using the product Admin UI, and then reindex the recipes that contain it.

To Reproduce
Steps to reproduce the behavior:

1. Go to the homepage.
2. Search for the word 'very'
3. Observe ingredients such as very ripe bananas

Expected behavior
The word very should not appear as a prefix for any autosuggested ingredients.

As with #69, this has mostly been resolved following some recrawling and reindexing of affected recipes; however, a few very ripe bananas stragglers remain in the search engine.

The remaining stragglers are due to #71, a blocker for resolution of this issue.

Manually resolved by clearing out (curl -XDELETE) stale documents with this problem. Issue #71 remains open for a longer-term fix.
