Migration to add entries to matviews table

There is no issue related to this. This change come from a discussion with @jkburges.
Is the `failOnError: false` to handle running this migration against production?  Perhaps a more liquibasey way of doing this would be to use a [precondition](http://www.liquibase.org/documentation/preconditions.html) which checks for the existence of the row?  I'd like to know if this works btw because I can do the same thing in a couple of the migrations I've got in my bug fix.
